本文对混合悬浮系统精确的数学模型进行了分析,分别对传统的PID直接反馈控制器和带状态观测器的状态反馈控制器进行了设计和比较,仿真结果表明,这两种控制器都能够使悬浮系统达到稳定,但是后者可以解决气隙速度信号估算的难题。
In this paper, the exact mathematical model of hybrid suspension system is analyzed. The traditional PID direct feedback controller and the state feedback controller with state observer are designed and compared respectively. The simulation results show that both of them can make The suspension system is stable, but the latter can solve the problem of air gap velocity signal estimation.
