摘 要: Among all the control algorithms of active magnetic bearing (AMB) system, PID controller is an important control method. This article introduced a methodology of finding all the stabilizing parameter set of PID controllers for AMB with time-delay by satisfying a robust performance constraint. The H-infinity index of additive weight uncertainty on the basis of robustness stability condition of closed loop system was first given by small gain theorem. Then, the parameter boundaries with the expected decay ratio index of PID controller were derived based on the boundary crossing theorem. The system can be stabilized and robustly satisfy the performance requirements by arbitrary choosing PID controllers parameter in the stability region. The proposed method reduced the difficulty of stability regions of PID parameters for AMB with time-delay system. Simulation and experimental results showed that the design method was effective.

在主动磁悬浮(AMB)系统的各类控制算法中,PID控制器是一种重要的控制方法。本文提出了一种方法,用于在满足鲁棒性能约束的前提下,求解具有时滞的AMB系统中所有稳定的PID控制器参数集。首先,基于闭环系统的鲁棒稳定性条件,利用小增益定理给出了加权不确定性对H∞指数的表达式。接着,依据边界穿越定理,推导出PID控制器期望衰减比指数下的参数边界。通过任意选择稳定区域内的PID控制器参数,系统可实现稳定并满足鲁棒性与性能要求。所提出的方案有效降低了具有时滞的AMB系统中PID参数稳定区域的复杂度。仿真和实验结果表明,该设计方法具有良好的有效性。
