中文摘要:考虑一类奇异离散系统,应用自适应遗传算法给出其降阶H∞ 控制器的设计方法。通过对目标函数的全局搜索,得到控制器的最小阶次及相应的正定矩阵参数,进而设计出降阶H∞控制器。仿真表明,所提出方法不论对非奇异系统,还是奇异系统都可以得到降阶H∞控制器,且控制器易于求解。

Reduced-order H∞ Controllers for Singular Discrete Systems Based on Adaptive Genetic Algorithm
Abstract:An approach of reduced-order H∞ controller for a class of singular disctete system is presented based on Adaptive Genetic Algorithm. The minimum order of the controller and a corresponding parameter pair of positive definite matrix are obtained by means of searching the object function. And then the reduced-order H∞ controllers can be constructed. The simulation results show that the controller can be obtained not only for non- singular system but also for singular system.
