五态控制器及其二阶对象的稳定性仿真分析

该文介绍五态控制器的模型、控制作用。五态控制器是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。将九种不同的二阶系统在五态控制器作用下进行稳定性仿真分析，可以得出结论：在五态控制器作用下通过改变作用力的大小，都可以使系统变为发散、等幅振荡、收敛稳定甚至使系统直接达到稳定状态而不管对象为何种二阶系统，也不管对象本身的稳定性特征(发散振荡、等幅振荡或稳定)。

Simulation Analysis of the Second-order System' Stability under the Five-state Controller Process

This paper introduced the five - state controller's model and its basic control actions. The controller divided the error phase - plane into nine working areas, in which the plant was controlled by five different rules. We took nine kinds of second order plants as the examples to introduce how the controller solves the stability problem. Two conclusions are obtained: (1) The controller possesses excellent performance; (2) Adjusting the control actions can make the system stability good and even no positive or negative overshoot, no matter whether the plant belongs to what kind of the second - order plants or the plant itself is not stable.
