摘要
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。针对此种情况,探讨了一种基于降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。
There is a close relationship between the control law and the state variables. The control law is often a function of some state variables. The problem that the control system can not work normally because of the incorrect control law is discussed. Because the measurement mechanism of the system is fault, the state variables which consist of the control law can not be obtained. Focusing on this matter, a way to reconstruct the control law based on the dimensionality reduction observer is given. Analysis and simulation is proposed for a control system. The result indicates that this way is effective.
