Book Description
Semi-Active Suspension Control Design for Vehicles presents a comprehensive discussion of designing control algorithms for semi-active suspensions. It also covers performance analysis and control design. The book evaluates approaches to different control theories, and it includes methods needed for analyzing and evaluating suspension performances, while identifying optimal performance bounds. The structure of the book follows a classical path of control-system design; it discusses the actuator or the variable-damping shock absorber, models and technologies. It also models and discusses the vehicle that is equipped with semi-active dampers, and the control algorithms. The text can be viewed at three different levels: tutorial for novices and students; application-oriented for engineers and practitioners; and methodology-oriented for researchers. The book is divided into two parts. The first part includes chapters 2 to 6, in which fundamentals of modeling and semi-active control design are discussed. The second part includes chapters 6 to 8, which cover research-oriented solutions and case studies. The text is a comprehensive reference book for research engineers working on ground vehicle systems; automotive and design engineers working on suspension systems; control engineers; and graduate students in control theory and ground vehicle systems. Appropriate as a tutorial for students in automotive systems, an application-oriented reference for engineers, and a control design-oriented text for researchers that introduces semi-active suspension theory and practice Includes explanations of two innovative semi-active suspension strategies to enhance either comfort or road-holding performance, with complete analyses of both Also features a case study showing complete implementation of all the presented strategies and summary descriptions of classical control algorithms for controlled dampers

Book Description
Vehicles handling and ride comfort are essential subject because these vehicles operate at different environments. Improving the comfortability enables the drivers to derive for a long time at critical situations with full activity. This work deals with dynamics and control policies analysis of semi-active suspension systems for off-road vehicles. Comprehensive comparison on three different configurations; 2-axle, 3-axle and 4-axle half-vehicle models were conducted to analyze the effect of using semi-active control policies. The application of several control policies of semi-active suspension system, namely skyhook; ground-hook and hybrid controls have been analyzed and compared with passive systems. Sprung mass acceleration, suspension deflection and tyre deflection responses were analyzed for measurements of ride quality and road handling. Analysis in frequency domain transfer function, time domain transient state and time domain steady state were conducted on each of the models.

Book Description
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.

Book Description
The main purpose of vehicle suspension system is to isolate the vehicle main body from any road geometrical irregularities in order to improve the passengers ride comfort and to maintain good handling characteristics subject to different road profile. This dissertation aim at establishing a mathematical model and a control strategy for a nonlinear hydraulically actuated active suspension system. A model of nonlinear, four Degree of Freedom (DOF) half vehicle active suspension system with hydraulic actuator dynamics and a similar nonlinear, four DOF half vehicle passive suspension system model was developed using Matlab/Simulink environment. A control system consisting of two controller loops was also developed, namely inner loop controller for force tracking control of the hydraulic actuator and outer loop controller to resist the effects of road induced disturbances. The outer loop controller employed a proportional integral and differential (PID) control strategy. On the other hand, a proportional integral and differential (PID) force feedback control scheme was employed in the inner loop controller to stabilize the hydraulic actuator in such a way that it is able to supply the actual force as close as possible with the optimum targeted force supplied by the PID controller. Two types of road (discrete and random) inputs were employed and a simulation study using Matlab/Simulink environment was performed to test the effectiveness and robustness of the control scheme. The performance of the active suspension system was assessed by comparing it response to that of passive suspension system. Results obtained shows that, the active suspension system developed a good dynamic response and a better ride comfort when compared to the conventional passive suspension system.

Book Description
This book focuses on most recent theoretical findings on control issues for active suspension systems. The authors first introduce the theoretical background of active suspension control, then present constrained H∞ control approaches of active suspension systems in the entire frequency domain, focusing on the state feedback and dynamic output feedback controller in the finite frequency domain which people are most sensitive to. The book also contains nonlinear constrained tracking control via terminal sliding-mode control and adaptive robust theory, presenting controller design of active suspensions as well as the reliability control of active suspension systems. The target audience primarily comprises research experts in control theory, but the book may also be beneficial for graduate students alike.

Book Description
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.
