永磁同步电机混沌系统的鲁棒PID控制

Robust PID control of chaos in permanent magnet synchronous motor

为了探讨多变量系统的H∞环路成形设计,基于遗传算法和伪对角化方法提出了一种权函数选取办法,并给出了将所得H∞控制器降阶成比列积分控制器的方法,设计了一种易于实现,且在参数摄动情况下仍然有效的控制器。仿真结果表明了该方法的有效性。

For the H∞ loop shaping design procedure of muhivariable system, a way of selecting weight functions is proposed based on the genetic algorithm and the Pseudo -Diagonalization. And a method is proposed to approximate H∞ controller with proportional integral controller. A controller is designed which is easy to realize and is effective under parameters perturbation. Simulation result shows the validity of the presented algorithm.
