闭环变量带误差系统的控制器设计

针对目前大多数系统的研究中，只考虑输出被误差干扰的情况，提出了一种闭环变量带误差系统模型(输入和输出信号均被噪声干扰),并对该系统的控制器进行设计。采用最小方差控制来对控制器进行设计，设计完成最小方差控制器以及自校正最小方差控制器。然后应用最小方差性能指标来评估控制器性能，并通过仿真验证控制器性能。

Controller Design for Errors-in-variables Closed-loop System

In view of the fact that the output is disturbed only by error in most of the current system research, a closed-loop variable system model with error (the input and output signals are disturbed by noise) is proposed, and the controller of the system is designed. In this paper, the minimum variance control is used to design the controller. The minimum variance controller and the self-tuning minimum variance controller are designed. Then the minimum variance index is used to evaluate the performance of the controller.
