Abstract

In this paper, a 1/4 vehicle suspension model with time-delay state feedback control is established, and the maximum time-delay allowed by different feedback gains in the control system is solved according to the Lyapunov stability theory. The stability of the vehicle suspension system is analyzed, and the vibration characteristics of the system are analyzed in the frequency domain and time domain. The simulation results show that the time-delay feedback control can effectively improve the damping performance of the vehicle suspension and improve the ride comfort of vehicle.
