Abstract: A controller was designed for the semiactive suspension system based on the Bouc—Wen model of magnetortheological fluid (MRF) damper. The controller consists of a system controller basing on LQR algorithm and a damper controller basing on Signum function method. Basing on Simulink simulation and compared with passive and active control, the semiactive cotrol algorithm shows good control effect.
Key words: magnetortheological fluid (MRF); semiactive suspension; damper controller; Signum function
