Abstract

This paper proposes a design method for vibration isolation control of a semi active suspension for automobiles. By using nonlinear functions we formulate the linear-parameter-varying system taking account of mechanical constraints such as valve stroke of the semi–active damper and the damping coefficient restriction. The gain-scheduled controller based on the linear matrix inequalities is obtained so that the closed–loop system may be stable and have good performance even if saturation of the valve stroke occurs. By simulations it is verified that the semi-active damper system designed is effective in comparison with either a passive damper or a conventional switching law based on H control.
