区间系数不确定性系统的鲁棒控制器设计

Robust Controller Design for Uncertain Systemswith Interval Parameters

本文提出了一种方法用于设计区间系数不确定性系统的鲁棒镇定控制器．所考虑的区间系数可以是时变的，控制器的设计仅依赖于区间系数的上下界，而设计步骤具有选代特征．虽然所提到的控制器是线性的和确定性的，但能够承受所有容允不确定性．所提出的方法通过一个电力系统负荷频率控制例子加以说明．

A method to design a robust stabilization controller for uncertain systems with interval parameters which can be time-varying is presented. Only the bounds of the system parameters are required to design the robust controller. The design procedure is iterative in nature andthe obtainded robust controller is a linear and fixed one but can tolerate all admissible uncertainties. The method is demonstrated by a power system load-frequency control example.
