摘　　要：使用发电厂钢球磨煤机进行实验,收集相关数据,获取辨识结果,以其为研究对象,在MATLAB/Simulink平台上分别搭建磨煤机控制系统的PID控制和模糊自适应PID控制的仿真模型获取仿真效果图像。针对控制系统的强相关性,提出单位矩阵法对该系统进行动态解耦经解耦可获得三个单回路,为三个单回路分别建立控制系统,优化对磨煤机出口温度控制、入口负压控制以及负荷控制方案。仿真结果表明:模糊自适应PID控制能有效改善控制效果。Based on MATLAB/Simulink platform,a simulation model of PID control and fuzzy adaptive PID control is built for the control system of mill based on the identification results of power plant ball mill.In view of the strong correlation of the control system,the unit matrix method is proposed for dynamic decoupling of the system.Three single loops can be obtained by decoupling.The control system is established for the three single loops respectively,and the control strategy of outlet temperature control,inlet negative pressure control and load control of the mill is improved.The simulation results show that the fuzzy adaptive PID control can effectively improve the control effect.
