摘要
烟叶复烤过程具有时滞、不确定、非线性特性,仅利用常规PID控制不能使复烤过程的各项性能指标满足要求,一种参数自适应模糊PID控制器能有效解决这一问题。该控制器的参数调整采用确定性的模糊调整规则,从而不仅使控制器的设计易于实现而且具有很强的适应性和鲁棒性。仿真结果表明,该控制器能对烟叶复烤过程进行有效控制。
The process of tobacco redrying has the characteristics of lagging, uncertainty and being nonlinear, so it is unable to satisfy every performance target only by using the usual PID controlling method. However, a kind of fuzzy PID controller with parameter adaptation can solve the problem effectively. The controller parameters are adjusted by using the crisp fuzzy adjusting rules, so that the design of the controller is easy to be realized, and at the same time it has strong adaptation and robustness as well. The result of the simulation shows that the controller can efficiently control the process of tobacco- redrying.
