| 摘 要： | 针对过程控制系统存在的非线性、纯滞后和负荷变化频繁的实际情况,提出了一种变积分系数的Fuzzy-PI控制器设计方法在系统的整个响应过程中模糊控制均存在,同时引入变系数的积分因子,构成Fuzzy-PI控制器.仿真结果表明,具有变积分系数的Fuzzy-PI控制器的过程控制系统既具有较快的动态响应,又有较高的稳态精度,而且整个响应过程具有很好的鲁棒性.

| Abstract: | A design of Fuzzy-PI controller with variable integral coefficient is stated, aimed to the process control system with nonlinear characteristic, pure delay and frequent load varying. This Fuzzy-PI controller is formed by the way that fuzzy control exists in the whole respond process and the integral factor with variable coefficient is added to the fuzzy control. Simulation results show that the process control system with this Fuzzy-PI controller with variable integral coefficient has more rapid dynamic responds and high static precision. The whole respond process has better robust. |
