基于全维观测器的系统控制律重构研究

在控制系统中,控制律与状态变量有着密切的关系,控制律往往是某些状态变量的函数.当控制系统的某些元件发生故障时,系统将无法得到构成控制律所需的状态变量,因而导致系统无法正常工作.针对此类情况,本文探讨了一种基于全维观测器的控制律重构方法,并针对某随动控制系统进行了分析和仿真,结果表明该方法是有效的.

Research of reconstruction of control law of system based on complete dimension observer

There is a close relationship between the control law and the state variables.The control law is of- ten a function of some state variables.This text is mainly about the problem that the control system can't work normally because the control law is incorrect.Because the measurement mechanism of the system is fault and the state variables which consist of the control law can't be acquired.Focusing on this matter, some work has been done about a way to reconstruct the control law based on the complete dimension ob- server.Some analysis and simulation is done about a control system.The result indicates this way is effec- tive.
