线性系统的定性控制方法

Qualitative Control Method for Linear Systems

根据被控对象的定性数学模型,设计一种定性控制器。精确数学模型是很难得到的,然而有很多对象,可知道它的工作机理,根据这种机理,能够建立定性数学模型,如果系统是线性的,将得到一种定性控制算法。利用这种定性控制方法,进行了大量的数字仿真,从仿真结果来看,控制的性能和鲁棒性都很好。这种控制算法适于工作机理已知且能写出线性微分方程的场合。

According to the qualitative mathematical model of the controlled process. a kind of qualitative controller is designed. According to the process running principle, qualitative mathematical model is estab-lished and a kind of qualitative algorithm for linear system can be obtained. Digital simulation results show the good control performance and robust. The control algorithm is best suited for knowing running principle and differential equation.
