摘　　要：在换热站温度控制中,由于系统温度控制具有非线性、大滞后、强耦合及系统参数容易改变等特点,传统的PID控制无法获得满意的控制效果,针对这一现象,采用参数自适应Fuzzy-PID的算法实现了对换热站温度的控制,利用模糊推理对ΔKp、ΔKi、ΔKd进行在线整定,仿真结果表明,该控制器取得了较好的控制效果。Considering the fact that temperature control system for the heat exchanger station has characteris- ticsof nonlinearity, big lag, strong coupling and changeable system parameters and the traditional PID control cant bring about satisfactory control effect, applying the parameter adaptive Fuzzy-PID algorithm to the heat exchange station temperature control was proposed and on-line regulating of Akp, Ak~ and Akd though fuzzy rea- soning method was implemented. The simulation results prove a better control effect of this controller.
