| Abstract: | A new improved RS-based neural PID controller is introduced in this paper.As It is difficult for RS-based neural PID controller to obtain the predicted output of the system, aiming for this defect, the new controller uses predicted mathematical model instead of actual output,and reduces redundant attributes and the values of a stylebook in BP network to keep important information by rough set;and the least stylebook is acquired which trains the neural network. Simulation results of the super heated steam temperature cascade control system show that the resistance and robustness of the system are good. |
