摘　　要：针对供热系统中二次网供水温度控制具有非线性、时变性、难以精确控制等缺点,结合模糊控制和PID控制的优点,采用变论域的思想,提出了变论域模糊PID算法。介绍了变论域模糊PID控制器的结构设计及伸缩因子的选择方法。经仿真实验表明,该控制方法使具有响应时间快、稳态精度高,及较强的抗干扰能力。该算法提高了二次网供水温度的控制精度,起到了节能降耗的作用。For the the second nets water supply temperature control with nonlinear, the time-varying, difficult to precisely control and the variable universe fuzzy PID algorithm other shortcomings in the heating system, com- bined with the advantage of the fuzzy control and PID control, is used variable universe thoughts and puts for- ward. The variable universe fuzzy PID controller structure design and stretch factor selection method are intro- duced. The simulation shows that the algorithm has fast response, high steady accuracy and better ability to oppose disturbances. The algorithm improves the control precision of the the second nets water supply temperature and have the function of saving energy consumption.
