二十七点九态控制器及跟踪仿真分析

二十七点九态控制器是根据偏差、偏差的变化和偏差变化的变化所构成的相空间上采用不同的控制作用以达到满足控制要求的控制器.分析此控制器的九种不同的作用力在相空间和响应曲线的一一对应关系,通过作用力来研究响应曲线,进而揭示出三阶及高阶对象难以控制的原因;通过不同的三阶对象分别在单位阶跃、正弦和斜波下的跟踪仿真,可得出结论：在此控制器作用下对于不同的三阶对象（含不稳定的）,可以达到满意的控制效果.

Twenty-seven-point-Nine-state Controller & Its Simulation Analysis

The twenty-seven-point-nine-state controller adopts different control actions to meet the demand based on the phase space which is made up of the system of error,the rate of error and the rate of the rate of error.We analyze the responding relation in the different actions of the controller between the phase space and responding curves,and explain why the third-order objects and high orders are difficult to be controlled through the action upon the curves.Emulation of step responding,sine wave and slope wave for different objects shows that it can realize effective control for different third-order objects.
