摘　　要：通过对二阶不稳定对象在五态控制器作用下的稳定性分析 ,介绍五态控制器的原理———根据偏差和偏差变化率的大小在相平面采用不同的作用力以达到控制要求的控制器。得到结论 :对于任意二阶不稳定对象 ,在五态控制器作用下 ,总可以找到一组合适的作用力 。This paper analyses the stabilization of the unstable second-order objects under the process of the five-state controller and introduced the five-state controller's principle-it is taken different force value to obtain the controlling demand on the phase plane by the value of error and error rate of the system.We discuss the unstable second-order objects,and conclude that the system can obtain the system stability requirement in the error permission range by adjusting the force value under the process of the five-state controller.
