摘　　要：锅炉温度具有大惯性、大滞后、非线性和时变性的特点,运行过程中扰动因素多、难控制.针对这种情况,文章综合了模糊控制和PID控制的优点,将SIMULINK与FUZZY TOOL BOX有机结合设计模糊自整定PID控制器.系统的仿真结果表明,该控制方法大幅度提升了对非线性、滞后性系统的控制效果,而且增强了系统的灵活性和适应性.Since boiler temperature having the characteristics of large inertia,time delay,nonlinear and time-varying,and it also being influenced by many disturbance factors,here,fuzzy auto tuning PID controller is designed by combining SIMULINK and fuzzy-tool-box organically.System simulation results show that the control method significantly improves on the non-linearity,hysteresis control effect of the system,enhances system flexibility and adaptability.
