Abstract: This thesis is concerned with the vibration attenuation problem of vehicle suspension systems and its extension to general vibration systems. Two research themes are considered: control methods for vehicle suspension systems and stability, performance analysis, and controller design for periodic piecewise linear systems. For vehicle suspension, control methods are proposed in order to improve ride quality, ensure ride safety and avoid structural damage. First, an adaptive suspension is designed with adjustable inerter, which can adaptively adjust its inertance. An H2 controller aiming at improving the suspension performances is designed to formulate the objective control input. The adjustable inerter adaptively varies its inertance under control to track this objective. Since the inerter cannot exert force to the system, which results in sub-optimal suspension performance, an active suspension with wheelbase preview is designed to enhance the performances. A multi-objective schme aiming at improving ride quality as far as possible subject to acceptable ride safety, avoiding structural damage and actuator saturation, is proposed for a half-car vehicle suspension model. Static output-feedback control is considered from an implementation point of view and an algorithm is presented to obtain the controller gain. Considering that the vehicle velocity may be uncertain or time-varying in practice, a multi-objective velocity-dependent controller is designed as an improved scheme. To treat the velocity as uncertainty or a time-varying parameter, robust controllers developed using homogeneous polynomial parameter-dependent approach and linear parameter-varying approach are proposed. Finally, a more realistic nonlinear full-car system with unknown dynamics characteristics is considered. Based on the successful application on a quarter-car test rig with active disturbance rejection control (ADRC), motion based ADRC is proposed to stabilize the vehicle body of the full-car model. Full-car dynamics are extracted as three interconnected subsystems, considering the heave, pitch, and roll motions. For each subsystem, an extended state observer is established to observe the total disturbance which captures the unknown internal dynamics and external excitation. A PD / Fuzzy-PD controller is constructed for the subsystem after compensating the total disturbance. Four actuator inputs are obtained in real time according to the three motion based controller outputs. For periodic piecewise linear systems, stability, stabilization, performance indices and controller design problems are investigated. First, two sufficient, and one necessary conditions concerning the exponential stability of periodic piecewise linear system with possibly non-Hurwitz subsystems are proposed. To facilitate the performance analysis and controller synthesis, a stability condition is established by employing continuous time-varying Lyapunov function. Based on the stability result, L2-gain and generalized H2 performance criteria are developed as well. By considering a more general formulation of Lyapunov function, that is, discontinuous Lyapunov function with time-varying Lyapunov matrix, stability, stabilization and L2-gain performance are studied by allowing the proposed Lypuanov function to be possibly non-monotonically decreasing over a period. A corresponding algorithm for the stabilizing controller is presented t

Download or read book Vehicle Suspension Systems and Electromagnetic Dampers written by Saad Kashem and published by Springer. This book was released on 2017-09-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Semi active Suspension Control written by Emanuele Guglielmino and published by Springer Science & Business Media. This book was released on 2008-05-27 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
