Semi-Active Suspension Improving Both Ride Comfort and Handling Feel

In recent years, as control technology is progressing, active control methods are introduced for the sake of the safety and ride comfort of cars. One of them is a semi-active suspension which has an important role to suppress vibration and to improve handling stability. In this paper, the steering feel of a driver is also improved in the framework of gain-scheduled H∞ control for a semi-active suspension. The control performance is confirmed by some experiments.
