基于模糊自适应 PID 的饱和蒸汽发电控制研究

摘要

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 control 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 PID 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 .%　　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。
