摘　　要：传统PID控制器参数的整定是在获取对象数学模型的基础上,根据某一整定规则来确定的,难以适应复杂多变的控制系统。文章应用模糊控制技术,设计一种二输入三输出自适应模糊PID控制器,对锅炉水位进行控制。利用MATLAB对控制系统进行仿真,结果表明,该控制器自适应能力及鲁棒性比传统PID控制器更强。The tuning of parameters for traditional PID controllers was based on the mathematical model of the object and on some rules, which was difficult to adapt to complicated and variable control systems. Fuzzy control technology was applied to design a two-input and three-output selfadapting fuzzy PID controller to control the water level of boilers. The designed system was simulated using MATLAB, and the results show that the self-adapting and robustness of the fuzzy controller are better than that of the traditional PID controller.
