Abstract

In this paper, a novel controller for the active suspension of a seven degrees freedom full-vehicle model is presented. The proposed Time Delay Auto-Synchronization (TDAS) controller is based on the delayed feedback control theory and it uses three accessible state variables to obtain stabilizing signals for damping heave, pitch and roll oscillations caused by terrain unevenness. For each input signal, it is required to determine the optimal values of time delay and gain. The performance of the TDAS controller is investigated via time domain simulations in MATLAB-Simulink.
