摘要
提出一种满足平方误差积分 (ISE)最小的闭环反馈稳定 PID调节器遗传优化设计方法。运用增广 Herm ite- Biehler定理 ,解析地给出了使任意给定 (稳定或不稳定 )被控对象闭环稳定的调节器参数取值范围。在该取值范围内运用遗传优化算法得到了满足指定性能指标 (ISE)最小的最佳调节器参数值。
A genetic optimization method of closed loop feedback stabilizing PID regulator with minimal ISE is proposed. With the generalization of Hermite Biehler theorem, the stabilizing domain of PID controller parameters for any given plant (stable or unstable) is given analytically. In this stabilizing domain, the optimal set of controller parameters that minimize the closed loop ISE criterion is selected by using of genetic algorithms. The simulation result shows the effectiveness of the proposed procedure.
