摘要
饱和蒸汽发电项目中汽轮机是一个典型的工业过程控制对象,具有时变、非线性和滞后等显著特点。基于汽轮机发电机运行过程的控制要求,提出了一种自适应模糊PID控制方法。结合汽轮机发电机运行和模糊PID控制解决非线性、滞后性及时变等问题的特点,基于从发电站现场采集到的数据,建立了控制模型,并利用MATLAB/Simulink对系统进行了仿真,从而验证了该方案的可行性,为发电机控制提出了一种新的方案。
The steam turbine in saturated steam power generation project is a typical industrial process control object, with the features such as time-varying, nonlinear and hysteresis. Based on the eontrol requirement of steam turbine generator operation, this paper put forward a kind of adaptive fuzzy PID control method. Combining the features of the steam turbine generator operation and fuzzy P1D controller, the paper analyzed the data collected from power station, established a control model, and carried out the simulation study by MATLAB/Simulink. The simulation results verify the feasibility of this scheme and lay a good foundation for the control scheme＇s application in generator operation process,
