“…A simple MR damper model is used allowing the scheduling of the damping coefficient nonlinearity in the control law. It is inspired in the work of [1] and [6] The electric current is the input signal that allows exploring in a full way the characteristics of the MR damper. Using this signal as the controller output and the chosen inputs, a complete exploration of the semi-active zone in the damper characteristic is ensured.…”

“…Hence, in such cases, the control strategy consists in the selection of the controller and the mapping algorithm. Seminal results show that a semi-active suspension can decrease up to 52 % of vertical sprung mass acceleration and up to 20 % of vertical sprung mass displacement, [1].…”

“…Some recent works are focused on the decrease in the compromise between comfort and road holding [4]. An interesting strategy is the LPV/H approach which solves the compromise adequately and with low on-line computation, [1], [5]. In this paper, a controller for an automotive semi-active suspension adaptable to the controllable shock absorber nonlinearities in order to ensure the full exploiting of the damping variability will be developed.…”

Abstract. The actual semi-active suspension control systems with a balance between comfort and road holding goals are not optimal because in these solutions one goal or the other always dominates in the suspension performance. This paper is centered in a new proposal to control an automotive semi-active suspension to achieve the comfort and maintain the road holding.The output in the control strategy is the electric current. A nonlinear quarter of vehicle model simulation compares and validates the proposal versus different controllers. The controller is designed with the H∞ criteria and the Linear Varying Parameter (LPV) considering the saturation and sigmoid shape of the F-V characteristic diagram. Unlike the solutions in literature, which use at least two scheduling parameters, the proposed LPV controller scheme for a semi-active suspension uses only one scheduling parameter.
