摘要

针对发电厂锅炉汽包水位具有非线性特性、存在虚假水位

且运行过程中控制系统超调量大、响应速度慢、抗干扰能力差等问题

提出了一种基于模糊推理的模型参考自适应内模控制(IMC)方法。将模糊控制方法和IMC方法相结合

采用相消法设计IMC器

根据参考模型输出与实际被控对象输出的偏差e及其变化率ec在线模糊调节PID参数。通过Simulink对基于模糊PID的模型参考自适应IMC的汽包水位控制系统进行仿真验证

并与IMC-PID的汽包水位控制系统进行对比。结果表明

基于模糊PID的模型参考自适应IMC方法自适应能力更强

抗干扰能力和鲁棒性更好

能够更好地保证水位的稳定。

Abstract

Against the problems of drum water level in utility boilers

such as nonlinearity and false water level

large overshoot

slow response speed and poor anti-interference ability of the control system during operation

a fuzzy inference based model reference self-adapting internal model control(IMC)method was proposed.By combining the fuzzy control with the IMC

this method uses the relative arithmetic to design the IM controller.It regulates the fuzzy adjusting PID parameters online according to the deviation e and its changing rate ec between the reference model output and the object's actual output.Moreover

on the basis of the Simulink platform

numerical simulation was performed to verify this drum water level control system using the above method.At last

the results were compared with that controlled by the internal model PID.The results show that

the fuzzy PID based model reference self-adaptive IMC has stronger self-adaptability

anti-interference ability and better robustness

which can guarantee the stability of the water level better.
