摘要
首先运用增广 Hermite- Biehler定理 ,解析地给出使任意给定 (稳定或不稳定 )被控对象闭环稳定的控制器参数取值域 .然后 ,在该参数取值域内运用遗传优化算法得到了满足指定混合 H2 / H∞ 性能指标的 Pareto最优控制器参数值 .仿真例子验证了该方法的有效性 .
Presents a global optimizing method of closed-loop unity feedback stabilizing fixed-structure(PID type)controllers with mixed \%H\-2/H\-∞\% performance. With the generalization of Hermite-Biehler Theorem, we can analytically obtain the stabilizing domain of PID controller parameters for any given plant(stable or unstable). Inside this stability domain, the optimal set of controller parameters was obtained by using of genetic algorithms. The simulation result shows the effectiveness of the proposed procedure.
