| 摘 要： | 提出一种评估带前馈的PID控制回路的控制器性能的方法.该方法通过求取在最优前馈和反馈控制器作用下的最小过程输出方差,并将其与实际的输出方差比较,以评估控制器的性能,同时可以得到实现该最小方差的最优PID控制器的参数.仿真结果表明,引入前馈作用可以改善PID控制回路的性能,并且采用本文提出的评估方法可以得到一个合理的评估结果.

| Abstract: | A method used tor assessing the controller performance of the PID control loop with feedforwara control was proposed. The minimum output variance of the optimal PID control loop with feedforward control was compared with the actual output variance for assessing the controller performance. Simultaneously, the parameters of optimal PID controller could be achieved. Simulation results show that the performance of the PID control loop is improved by introducing feedforward control,and the performance index is reasonable when the method proposed is used. |
