基于行为方法的广义系统可控性分析

Analysis of controllability for descriptor system based on behavioral approach

针对广义描述的线性系统,重新定义控制变量和受控变量,得出明显对象行为及其隐藏行为的核描述.借助适当引理得到使系统可控或可镇定的充分必要条件,这个结果使得对系统进行任意极点配置和使其镇定的控制律设计成为可能.并将此结果推广到一般形式描述的线性系统.

The control variable and the controlled variable were redefined for the descriptor system. Kernel representations of manifest plant＇ s behavior and hidden behavior are acquired. The sufficient and necessary conditions for the controllability and stabilization of this system are achieved by the suitable lemmas, this result make it possible to design control law for pole placement and stabilization, and can be applied in system represented in general form.
