离散时间系统多模型切换控制器

Multi Model Switching Control of Discrete Time System

基于离散时间系统模型，提出一种切换控制器，这种控制器可保证经过多次切换，系统的状态是Ｌｙａｐｕｎｏｖ 稳定的·同时针对被控对象参数不确定范围对被控对象建立多个模型，每一个采样时刻根据输出误差，选择最优模型及切换控制器，避免了切换控制器造成的切换频繁、过渡时间过长的弊端。

A kind of switching controller based on discrete time system was proposed,and this kind of controller can guarantee the stability of the state variables after finite switches. Multiple models according to the uncertain scope of the system parameters were set up to improve the transient response. At every switching time, the differences between the outputs of multi models and the output of the system can be used to decide the best controller.
