线性跟踪系统的控制律

On the control laws of linear delay systems

利用线性系统的叠加原理 ,将理想输入表示为从不同采样时刻开始的系统的单位阶跃响应的线性组合 ,求得组合系数并由此导出了跟踪系统的控制律。理论分析表明 ,采用这种控制律可实现对系统的精确控制 :无超调、无静差。

By means of the additivity principle of linear systems, the ideal input is represented to be the linear combination of unit step response starting from different sampling periods, the combination coefficients are obtained and the numerical expression of the tracking control law is given out. Theoretically, the control law can make the tracking systems to be controlled precisely: over regulation, static error and transition time are all zero.
