摘要：

In this paper we compare various H infinity controllers, which differ in the way they exploit preview information about road irregularities. To this end, we introduce several linear models of the quarter car that incorporate the delay between sensing the road disturbance in front of the car and the arrival of the disturbance at the wheel in different ways. Based on these models, we design and compare feedforward controllers and feedback controllers coupled with a feedforward portion. For this, we use standard Hoc control methodology as well as an H infinity method for time delay systems. The latter is capable of coping with a varying time delay. We investigate the controller performance in simulations and discuss the influence of varying time delay on the performance.
