摘要：

In this paper a new approach to the design of an active four-wheel-steered (4WS) control system is introduced. The problems of the conventionally used LQ-controller-based virtual model following control strategies are analyzed, and several problems are addressed. Two main problems of the LQ controller are highlighted: the external disturbance rejection, and the robustness of the controlled system in the face of parametric uncertainties. In the paper a combined Robust Linear Quadratic Regulator (RLQR) and H-infinity controller design is presented for an active 4WS vehicle. The applicability of this kind of controllers is proven in this particular design case.
