Semi-active Suspension Control provides an overview of vehicle ride control employing smart semi-active damping systems. These systems are able to tune the amount of damping in response to measured vehicle-ride and handling indicators. Two physically different dampers (magnetorheological and controlled-friction) are analysed from the perspectives of mechatronics and control. Ride comfort, road holding, road damage and human-body modelling are studied. Mathematical modelling is balanced by a large and detailed section on experimental implementation, where a variety of automotive applications are described offering a well-rounded view. The implementation of control algorithms with regard to real-life engineering constraints is emphasised. The applications described include semi-active suspensions for a saloon car, seat suspensions for vehicles not equipped with a primary suspension, and control of heavy-vehicle dynamic-tyre loads to reduce road damage and improve handling.

With the new advancements in the vibration control strategies and controllable actuator manufacturing, the semi-active actuators (dampers) are finding their way as an essential part of vibration isolators, particularly in vehicle suspension systems. This is attributed to the fact that in a semi-active system, the damping coefficients can be adjusted to improve ride comfort and road handling performances. The currently available semi-active damper technologies can be divided into two main groups. The first uses controllable electromagnetic valves. The second uses magnetorheological (MR) fluid to control the damping characteristics of the system. Leading automotive companies such as General Motors and Volvo have started to use semi-active actuators in the suspension systems of high-end automobiles, such as the Cadillac Seville and Corvette, to improve the handling and ride performance in the vehicle. But much more research and development is needed in design, fabrication, and control of semi-active suspension systems and many challenges must be overcome in this area. Particularly in the area of heavy vehicle systems, such as light armored vehicles, little related research has been done, and there exists no commercially available controllable damper suitable for the relatively high force and large displacement requirements of such application. As the first response to these requirements, this thesis describes the design and modeling of an in-house semi-active twin-tube shock absorber with an internal variable solenoid-actuated valve. A full-scale semi-active damper prototype is developed and the shock absorber is tested to produce the required forcing range. The test results are compared with results of the developed mathematical model. To gain a better understanding of the semi-active suspension controlled systems and evaluate the performance of those systems, using perturbation techniques this thesis provides a detailed nonlinear analysis of the semi-active systems and establishes the issue of nonlinearity in on-off semi-active controlled systems. Despite different semi-active control methods and the type of actuators used in a semi-active controlled system, one important practical aspect of all hydro-mechanical computer controlled systems is the response-time. The longest response-time is usually introduced by the actuator -in this case, controllable actuator - in the system. This study investigates the effect of response-time in a semi-active controlled suspension system using semi-active dampers. Numerical simulations and analytical techniques are deployed to investigate the issue. The performance of the system due to the response-time is then analyzed and discussed. Since the introduction of the semi-active control strategy, the challenge was to develop methods to effectively use the capabilities of semi-active devices. In this thesis, two semi-active control strategies are proposed. The first controller to be proposed is a new hybrid semi-active control strategy based on the conventional Rakheja-Sankar (R-S) semi-active control to provide better ride-handling quality for vehicle suspension systems as well as industrial vibration isolators. To demonstrate the effectiveness of this new strategy, the analytical method of averaging and the numerical analysis method are deployed. In addition, a one-degree-of-freedom test bed equipped with a semi-active magnetorheological (MR) damper is developed. The tests are performed using the MATLAB XPC-target to guarantee the real-time implementation of the control algorithm. The second controller is an intelligent fuzzy logic controller system to optimize the suspension performance. The results from this intelligent system are compared with those of several renowned suspension control methods such as Skyhook. It is shown that the proposed controller can enhance concurrently the vehicle handling and ride comfort, while consuming less energy than existing control methodologies. The key goal of this thesis is to employ the existing knowledge of the semi-active systems together with the new ideas to develop a semi-active suspension system. At the same time, development of an experimental simulation system for real-time control of an experimental test bed is considered. To achieve its goals and objectives, this research study combines and utilizes the numerical simulations and analytical methods, as well as lab-based experimental works. The challenge in this research study is to identify practical and industrial problems and develop proper solutions to those problems using viable scientific approaches.

This book describes the development of a new analytical, full-vehicle model with nine degrees of freedom, which uses the new modified skyhook strategy (SKDT) to control the full-vehicle vibration problem. The book addresses the incorporation of road bank angle to create a zero steady-state torque requirement when designing the direct tilt control and the dynamic model of the full car model. It also highlights the potential of the SKDT suspension system to improve cornering performance and paves the way for future work on the vehicle’s integrated chassis control system. Active tilting technology to improve vehicle cornering is the focus of numerous ongoing research projects, but these don’t consider the effect of road bank angle in the control system design or in the dynamic model of the tilting standard passenger vehicles. The non-incorporation of road bank angle creates a non-zero steady state torque requirement.

The design of vehicle suspension systems is an active research field in which one of the objectives is to improve the passenger's comfort through the vibration reduction of the internal engine and external road disturbances. Comfort and road handling in car can be improved by including a semi-active suspension system, controlled by varying the damping based on measurements of the vehicle motions. This research deals with design and development of a quarter-car suspension using magneto-rheological damper (MR). A quarter-car of two degree-of-freedom (DOF) system is designed and constructed on the basis of the concept of a four-wheel independent suspension to simulate the actions of a semi-active vehicle suspension system. The selection of an appropriate MR damper model is crucial, since it provides the suitable current and force relationship and allows finding the appropriate force to the system. The behavioral characteristic of selected MR damper model is simulated and analyzed with different current input. An effective control structure is a key function of this research to determine the complexity of the control design and parameter tuning process. The performance of Proportional Integral Derivative (PID) and Linear Control Regulator (LQR) controller is designed based on the system requirements. In this research, the PID controller is verified experimentally under different road excitations to improve the ride quality and vehicle safety.

By forming the link between the road surface and the vehicle, the chassis plays a key role in enhancing vehicle dynamics and ride comfort. With its control systems, it provides the basis for the further development of driver assistance systems which support the driver in the task ofdriving the vehicle. This applies to an even greater extent to autonomous vehicles. Electromechanical steering and steerby-wire systems are one solution available. At the sametime, the brake system as a safety component needs to be developed in such a way that it fulfills the requirements of powertrain hybridization and electrification.

This research is mainly about the control design, analysis, and simulation of a vehicle suspension system. In order to decrease the vibration of the vehicle, a passive suspension system, semi-active suspension system, and active suspension system are taken into consideration. The central idea is based on the combination of a nonlinear energy sink and a skyhook. The car performance such as car body acceleration, suspension deflection, and wheel deflection are measured to compare the proposed control with a passive suspension system, a skyhook suspension system (semi-active suspension system), and a nonlinear energy sink suspension system (active suspension system). According to the comparison, it shows that the proposed system comprised of a nonlinear energy sink and skyhook achieves better performance with regards to the performance objectives. Based on the result, a hydraulic actuator is applied to mimic the force obtained from the proposed suspension system. Three control methods are utilized to achieve the purpose. The first control input is designed by using a singular perturbation technique combined with adaptive control. The second control method is based on multiple surface sliding mode control. By designing two sliding surfaces, an ideal tracking performance can also be obtained. Lastly, model predictive control is utilized, which can be treated as a special optimal control. By optimizing the cost function involved in tracking error and control input at each sample time, an ideal control input can be obtained from it. The first two methods are supported by Lyapunov based stability analysis to prove that the tracking error will approach zero asymptotically. Simulation results for each method are also given to show the vehicle performance and tracking performance.

This book contains thirty timely contributions in the emerging field of Computational Intelligence (CI) with reference to system control design and applications. The three basic constituents ofCI are neural networks (NNs). fuzzy logic (FL) I fuzzy reasoning (FR). and genetic algorithms (GAs). NNs mimic the distributed functioning of the human brain and consist of many. rather simple. building elements (called artificial neurons) which are controlled by adaptive parameters and are able to incorporate via learning the knowledge provided by the environment, and thus respond intelligently to new stimuli. Fuzzy logic (FL) provides the means to build systems that can reason linguistically under uncertainty like the human experts (common sense reasoning). Both NNs and FL I FR are among the most widely used tools for modeling unknown systems with nonlinear behavior. FL suits better when there is some kind of knowledge about the system. such as, for example, the linguistic information of a human expert. On the other hand. NNs possess unique learning and generalization capabilities that allow the user to construct very accurate models of nonlinear systems simply using input-output data. GAs offer an interesting set of generic tools for systematic random search optimization following the mechanisms of natural genetics. In hybrid Computational Intelligence - based systems these three tools (NNs, FL, GAs) are combined in several synergetic ways producing integrated tools with enhanced learning, generalization. universal approximation. reasoning and optimization abilities.

In this manuscript, the main objective is to obtain improved active suspension control for the full car model. A car suspension may be classified as passive suspension, semi-active suspension and active suspension system. Mathematical modeling of the passive suspension, semi-active suspension and active suspension for the full car suspension control are evaluated. Then three models of car suspension, i.e., quarter car, half car and full car models are explained. The spring and damper of the conventional passive suspension and semi-active suspension are fixed. Due to this drawback, the passenger comfort and vehicle handling is affected against the road disturbances. To resolve this drawback active suspension for full car model is explained. An active suspension consists of actuator. The controller drives the actuator, which depends on the proposed control law. The active suspension system gives the freedom to tune the whole suspension system, and the control force can be initiated locally or globally depending on the system state. Then active suspension systems provide more design flexibility and increase the range of achievable objectives.
