| 摘 要： | 为了克服常规PID控制器的缺点．提出了一种简化的模糊PID控制策略。首先利用扩充临界比例带法将PID公式简化为只有一个控制参数蜘，然后通过模糊控制规则和模糊推理确定一张模糊控制表。在实时控制中通过查询模糊控制表，在线调节参数和，可以提高PID控制算法的适应性和鲁棒性。对比仿真试验的结果表明，简化的模糊PID控制器的控制性能明显优于常规PID控制器。

| Abstract: | In order to overcome the shortcomings of conventional PID controller, a simplified fuzzy PID controller is proposed. First, the PID tormula was simplified to one parameter Kp by adopting expanded critical proportional band, then a fuzzy control table was designed by using fuzzy control rule and fuzzy inference theory. Through adjusting the parameter Kp online with querying the fuzzy control table,flexibility and robustness of the PID control algorithm can be enhanced. In comparison with simulation experiments, the results show that the performance of the simplified fuzzy PID controller is better than that of the conventional PID controller. |
