摘　　要：超临界锅炉主汽温度具有大惯性、大滞后和非线性的特点,用传统的PID难以达到理想的控制效果。将模糊控制和PID结合起来,既保留了串级控制抗内扰的性能,又结合了模糊控制动态性能好的特点。仿真结果表明,用模糊-PI串级控制超临界主汽温具有较好的控制品质和较强的抗扰能力。As the main steam temperature of supercritical boiler has characteristics such as large inertia, hysteresis and non-linear,it is difficult to achieve the desired effect with traditional PID control. The combination of fuzzy control and PID has retained the anti-disturbance performance of cascade control,and combined the good performance of fuzzy dynamic control. The results of simulations show that using Fuzzy-PI cascade control in supercritical steam temperature control can get better quality and stronger immunity.
