| Abstract: | The long time-delay often exists in industrial process.In order to overcome the big overshoot and long regulating time of the long time-delay system control,a new fuzzy self-adaptive PI-Smith control method is proposed.This method combines the Smith predictive control with fuzzy self-adaptive proportional-integral(PI)control.The traditional proportional-integral-derivative(PID)controller in Smith predictive control is replaced by fuzzy PI controller which utilizes the principle of fuzzy control to tune para... |
