线性闭环系统的动态性能分析

Analysis of Dynamic Behaviour in the Linear Closed System

采用状态反馈实现线性闭环系统的极点配置。着重研究线性闭环系统传递函数的零点、能控性、能观性和极点分布,以及多变量系统的零极点相消等问题。并通过实例予以阐明。这些都与观测器的设计很有关系,有一定的参考价值。

In order to get the desired dynamic behaviour by designer, We should use the assignment of poles of linear closed systems by means of state-feedback of the systems. This paper study the problems about zeros of transfer functions in the closed system, and controllability, observability, the location of poles, and the pole-zero cancellation of the transfer function for multivariable-system,which have much to do with the design of observer. This paper explains this fact by physical examples.
