Abstract :In this paper, the problem of reference tracking was investigated for a road simulator system from the perspective of control theory. The suggested control signal is obtained from a nonlinear backstepping control algorithm. This design is used to mirror the road displacement signal in the test system containing a vehicle system that incorporates a hydraulic piston. The performance of the proposed controller is evaluated in the time and frequency domains, with the primary criterion being that the displacement of the test road irregularities created by the hydraulic piston is accurately reflected to the vehicle. Additionally, the frequency densities of the signals transmitted to the vehicle are expected to match the real road data. Real road signals for land vehicles are used as the reference input signals. We demonstrate the effectiveness of the control signal through the results obtained in a laboratory environment.
