STUDY OF ADAPTIVE CONTROL ALGORITHM EMPLOYING HYSTERETIC MAGNETO-RHEOLOGICAL DAMPER MODEL IN ¼ CAR SUSPENSION

Úradníček J., Musil M.
pages 248 - +11p., full text

This paper presents a study of the semiactive adaptive control algorithm through numerical simulation where the adaptive control is compared to the skyhook control, active LQR, semiactive LQR and passive suspension. A hysteretic magneto-rheological (MR) damper model is proposed so that sensitivity of the system variables with respect to the control variable can be evaluated for the purpose of employing the adaptive control algorithm based on the gradient search method. This study includes discussions of the MR damper model setup ¼car suspension model setup, controller setup and dynamic analysis approach. The effectiveness of all controllers and passive suspension is demonstrated through simulations.
