ABSTRACT

This paper investigates the vibration attenuation problem of a vehicle suspension test rig, aiming at stabilizing its attitude. In the presence of nonlinear and unknown system dynamics, an accurate mathematical model of the test rig is not available. Active disturbance rejection control is employed to design a controller. An extended state observer is established to estimate the total disturbance which will be compensated in the controller design. The method will be very useful in industrial applications of active vehicle suspension because of its good robustness and easy implementation. Experimental results under different road profiles are used to validate the merits of the proposed control method.
