高速車両支持系の最適アクティブ制御 : 空気圧アクチュエータを有する二自由度系の解析

抄録

Actively controlled suspensions are required to realize a high stability and a high ride quality for high speed ground vehicles running on a rough surface. Recently actively controlled suspensions have been researched and developed for automobiles, railway cars and magnetically levitated vehicles. In this paper, optimal control systems for a two-DOF model of vehicle suspension are designed by optimal regulator theory, considering the dynamic characteristics of an air spring and a pneumatic actuator. Stability, ride quality and control input are discussed through frequency response and power spectral analysis.
