Ride Comfort Performance of Active Vehicle Suspension with Seat Actuator Based on Non-Fragile H∞ Controller
(*) Corresponding author
The purpose of this paper is to investigate an active seat suspension system with two active actuators using a non-fragile robust control strategy. A simple deterministic vibration model of human body is added to the seat suspension dynamical model in order to make the modeling more accurate. Desired controller is obtained by solving a linear matrix inequality formulation by considering the vertical body acceleration as measurement signal. Finally, the effect of the seat actuator and controller gain variations on the closed-loop system performance is investigated numerically for two deterministic external excitations: bump and a realization of Gaussian white noise. Simulations show that the seat actuator has a noticeable effect on the seat suspension performance especially under random disturbances.
