This paper describes a simulation design procedure aimed to achieve improved performance of the vehicle semi-active suspension. The issues related to the design of vehicle models with skyhook control are discussed. Three basic models with linear parameters are explained: quarter-, half-and full-car. The road profile is generated from a spatial power spectral density (PSD) to represent a typical road (based on ISO 8608 classification). The normalized root-mean-square values of sprung mass acceleration and tyre load forces are used to assess the vehicle ride comfort and handling performance based on five benchmark road profiles employed in industrial tests.

This paper develops a systematic methodology for the control of a class of nonlinear systems and applies it to an electrohydraulic system. The class of systems to be dealt with are those that are single input and can be put in strict feedback form. The approach is conceptually similar to previously developed integrator backstepping methodologies. However, unlike some previous investigations which have relied exclusively on a Lyapunov analysis, this work presents a stability analysis using a passivity formulation. There are two main advantages of the proposed approach which become significant during implementation. One practical advantage is that the resulting controller leads to synthetic inputs that are decoupled in a certain sense. This leads to a compartmentalization of modeling error effects associated with the controller. A second advantage of this method is that the system model need not be differentiated in the control formulation. A class of modeling error is introduced and compensated for with the resulting control able to guarantee specified boundary layer tracking. A nonlinear model is developed and verified for an electrohydraulic testbed consisting of a cylinder governed by a electronically controlled servovalve. Finally, the control algorithm is implemented on the testbed and a comparison is made with existing integrator backstepping algorithms. The comparisons demonstrate the benefits of the presented approach.Index Terms-Electrohydraulics, passivity-based control, strict feedback form systems.

Abstract-An investigation is conducted into the performance of passive, semi-active and active electromagnetic dampers. Theoretical models are constructed of the dampers and these are included in two degree of freedom models of the suspension. The passive and semi-active electromagnetic dampers are significantly heavier than commercial hydraulic dampers. In the case of active electromagnetic damper, the reduction in passenger acceleration is 88 percent when compared to passive damper and 61 percent when compared to a semi-active damper. The power consumption is similar to a magnetorheological semi-active damper.
