摘要
针对传统的ＰＩＤ控制、模糊控制和双模开关式Ｆｕｚｙ－ＰＩ控制的不足，提出了一种新的控制方案，即智能Ｆｕｚｙ－ＰＩ控制（ＩＦＰＩＣ）。仿真结果表明，该方案优于双模开关式Ｆｕｚｙ－ＰＩ控制和单个的模糊控制以及ＰＩＤ控制，具有较好的动态响应性能、良好的稳态控制精度和强的鲁棒性；此外，也降低了对Ｆｕｚｙ控制器的设计要求。其设计方法具有一般性。
This paper puts forward a new control version, intelligent Fuzzy-PI control (IFPIC). An intelligent monitor is designed in accordance to the error and its change. The monitor adopts fuzzy reasoning technique, supervises and adjusts the proportion of fuzzy control to PI control in real time, thus intelligentizing whole control. Simulation results show that the control version is superior to traditional PID control, fuzzy control and double switched Fuzzy-PI control, and has a better dynamic response performance, a good steady-state control accuracy and strong robustness.
