摘　　要：针对电厂主汽温控制系统扰动量多、抗干扰能力弱等问题,在常规控制系统中增加模糊环节,形成Fuzzy-PI控制器,并将其控制效果与常规PID控制器的控制效果进行对比。仿真试验表明:Fuzzy-PI控制器对主汽温系统响应时间、超调量等重要指标的控制效果明显优于常规PID。To solve the problems that a large number of disturbances exist in the main steam temperature control system of a power plant with poor anti-jamming capability, a fuzzy link was added to the control system, thus forming the Fuzzy-PI controller, of which the control effects were compared with that of the conventional PID. Simulation results show that the Fuzzy-PI controller has better control effects over conventional PID in following important indicators, such as the response time, overshoot and so on.
