摘要：

This article presents a new disturbance compensator and its application to vibration damping of a quarter car. First, we introduce an optimal feedforward preview controller. It is based on an impulse response model of the system dynamics and can be calculated analytically. The advantages of this feedforward controller are its simple parametrization via an objective function and its ability to use preview data. Then, we present how to design the disturbance compensator using the feedforward controller. In the second part, we apply the compensator to vibration damping of the quarter car. Therefore, we analyze the influence of some parameters on the performance of the compensator. Finally, we show that the disturbance compensator leads in simulation as well as in experiment to a remarkable damping of oscillations.
