摘要
在电厂中,必须严格控制过热器出口蒸汽温度,蒸汽温度过高或过低,都将给安全生产带来不利影响。针对过热汽温被控对象的特点,充分利用模糊控制的动态特性好和PID调节能消除静态偏差的特性,设计了一种带自调整因子的模糊控制器,研究了Fuzzy-PID复合串级控制在电厂过热汽温控制系统中的应用。仿真结果表明,Fuzzy-PID复合串级控制系统具有更好的抗干扰能力和适应性。
According to the temperature features of super-heated steam, a fuzzy controller with an adjustable factor is designed. The application of Fuzzy-PlD composite control in the super-heated steam temperature system of power plant is primarily studied by fully use of both the good dynamic characteristics of fuzzy con- trol and eliminating static deviation of PID control. The results of simulation indicate that Fuzzy-PlD composite cascade control system will have powerful anti-disturbance capacity and adaptability.
