摘　　要：燃气热水器的水加热过程是非线性、时变的纯延迟控制过程,在燃气热水器水温控制系统中采用传统的PID控制算法进行温度控制难以达到满意的效果。本文提出一种采用模糊算法在线自动整定PID参数的方法,实现了燃气热水器水温的高精度恒温控制。结果表明:采用模糊PID算法的控制器响应快,超调小,控制效果更好。The water heating process of gas water heater is non-lineal, time-varying, delay control process. It can not achieve satisfying effect using traditional PID algorithm to control water temperature in the water temperature control system of gas water heater, This paper presents a method for regulating PID parameters on line automatically with fuzzy algorithm to realize controlling water high precision constant temperature of gas water heater. The result shows that the controller with fuzzy PID algorithm gives a better performance with reduced reaction time and little overshoot temperature.
