多输入控制振动系统的多步反向极点配置法

在多步极点配置的基础上,为实现系统部分极点的重新配置,引入了反向极点配置策略。同时对欲配置极点选择采用频率靠近低频值的处理,这样不仅系统不会出现控制力很大的现象,而且系统配置很容易实现,这对于振动主动控制系统的实现具有实际的意义,同时该方法具有思路简单、可操作性较强的特点。算例表明该方法是有效的。

Inverted Pole Assignment in Vibratory Systems by Multi-Input Control

Based on pole assignment of multi input control, an inverted strategy of pole assignment is introduced to realize reassigning some poles of a vibratory system. Meanwhile, the closely lower frequencies are adopted as reassigning some poles, that not only the phenomenon of excessive control force can be avoided, but also reassigning some poles can be easily realized. It has practical significance to active vibration control. The method is characterized by its simple clue and high maneuverability. An example is presented to show the effectiveness of the method.
