最小方差自校正控制仿真研究

文章主要介绍了自校正控制和最小方差自校正控制的基本原理,设计用Matlab软件在计算机上如何完成最小方差控制的算法。被控对象参数往往是未知的,利用自校正控制技术,可以在线实时辨识参数,使输出量的稳态值方差最小,并和常规PID控制进行比较,体现出最小方差自校正控制的优越性。最后通过Matlab软件在Simulink环境下对其进行仿真研究。

Minimum Variance Self-tuning Control Simulation

This paper recommend the basic principles of the self-tuning control and the minimum variance self-tuning control,and designed how to complete the minimum variance control algorithms on a computer by Matlab software.The object parameters are often unknown but we can identification the parameters online real-time by using self-tuning control technology,So we can get the least impact on the system,and achieve a steady output value of the minimum variance.Compared with conventional PID,we will find the superiority of minimum variance self-tuning control.Finally,we use the Simulink environment of Matlab software for its simulation.
