Application of Genetic Algorithm to Mixed H 2/H ∞ Optimization Control Design

介绍了现已成为关键智能计算之一的一种新的全局优化搜索算法—遗传算法，并探讨了在混合Ｈ２／Ｈ∞最优指标下优化控制设计中的应用。其最大特点是：本质并行、全局优化，它不要求目标函数连续和可微，比梯度法和随机搜索算法更适合于ＰＩＤ混合Ｈ２／Ｈ∞优化问题。

Genetic algorithm,as a new global optimization searching algorithm which becomes one of vital intelligent computation,is introduced here.The application of this algorithm to mixed H 2/H ∞ optimization index control design is studieded. The algorithm has the advantage of parallel in neture and global optimization,and has no demand for continuous and differentiable object function.This gradient algorithm and randam searching algorithm in are more suitable mixed PID H 2/H ∞ optimization problem.
