Actively controlled air suspensions are expected to improve the' ride quality and stability of high-speed ground vehicles. In this paper, feedback control systems are discussed for active air suspensions by designing both a proportional-integral controller and an optimal regulator with a state observer. These feedback controllers are designed and realized by a microcomputer, to which the acceleration of a suspended mass is inputted, and which operates a pneumatic actuator by the pulse width modulation. An experimental set-up is constructed and the vibration isolation is examined by a test stand. The results are compared with those from theoretical calculations. According to this comparison, it is found that the model is verified and the vibration isolation is greathy improved.
