摘　　要：针对传统的PID控制器依赖被控对象精确的数学模型,当应用在复杂的、非线性、大迟滞的即热式热水器时难以达到良好的动态响应的缺点,将模糊控制理论应用于即热式热水器的温度控制中,同时分析了即热式热水器控制系统硬件组成及工作原理,并且在MATLAB中应用Fuzzy Toolbox和Simulink对控制系统进行仿真。实验结果表明,模糊控制方法相对于传统的PID控制具有更好的动态和静态性能,控制精度也大为提高。Traditional PID controller relies on the accurate mathematical model of the controlled object.When it is used in items with complex and non-linear delay such as instantaneous water heater,it is difficult to achieve positive dynamic response.In this paper,the fuzzy control theoryis applied to the temperature control of the instantaneous water heater.The hardware and operating principle of the control system are analyzed.The control system is simulated using Fuzzy Toolbox and Simulink in MATLAB.It＇s shown that the fuzzy control method has better dynamic and static properties and accuracy in its control compared with the traditional PID control.
