【摘要】 常规PID控制器不能在线整定参数,当对象存在结构非线性、参数时变性或模型不确定时,其参数更加难以整定,且最佳参数容易漂移,以变风量空调房间为研究对象,采用模糊控制与PID控制相结合,构成模型自整定PID控制器,利用模糊控制器在线调整PID控制器的参数进行大量的仿真研究,然后在仿真实验的基础上将其应用于实际控制。更多还原

【Abstract】 The PID controller can’t adjusting parameters online and its optimum parameters are inclined to drift with nonlinear, time variable or uncertain model system. Combining PID with fuzzy theory with researching on the VAV air conditioned room, the Fuzzy self tuning PID controller is proposed. Before application, a lot of simulation experiments upon fuzzy controller to identify the parameters of PID controller is performed.更多还原
