- Abstract
- The main objective of vehicle suspensions is to improve ride comfort and road holding ability. Though passive suspensions consist of spring and damper, active suspensions adopt an actuator in addition to passive suspensions. In this paper, a quarter car model with an asymmetric hydraulic actuator is used. Moreover, the damping coefficient of the damper. which is changed according to the actuator velocity, is considered, The LPV (Linear Parameter Varying) model is obtained by applying feedback linearization technique. Next. a gain-scheduled controller. based on LQ regulator with different weighting factor, is designed according to the actuator velocity and the stability of the proposed controller is also proved. The effectivenes of the proposed controller is shown by numerical simulations.
