摘　　要：通过二维模糊控制器的实际输出,对PID控制器的参数进行在线修正,在此基础上,进一步设计出基于PSO的模糊自适应PID控制系统,同时在MATLAB环境下建立了主蒸汽温度-给煤量优化系统的仿真模型。从而在模糊自适应PID控制器的基础上具备更加优越的动态性、抗干扰性和鲁棒性。最后采用MATLAB软件中的simulink工具建立了锅炉主蒸汽控制器仿真模型,仿真结果表明:基于PSO的模糊自适应PID控制方法具有较好的动态性能及稳态性能。By actual output of two-dimensional fuzzy controller, the parameters of PID controller are modified online. On this basis, the fuzzy adaptive PID control system based on PSO is designed, and main steam temperature is established in MATLAB environment. Simulation model of the coal supply optimization system. Therefore, based on the fuzzy adaptive PID controller, it has superior dynamic, anti-interference and robustness. Finally, the simulation model of boiler main steam controller is established by using Simulink tool in MATLAB software. The simulation results show that the fuzzy adaptive PID control method based on PSO has better dynamic performance and steady state performance.
