Abstract: For the problem that common PID control hardly solves the problems of time delay and nonlinear in actual industry system,the paper proposed a design scheme of discharging system of jigger based on T-S fuzzy model.It introduced components of the automatic discharging system of jigger,analyzed identification principle of T-S fuzzy model and expounded modeling and simulation of the discharging system of jigger based on T-S fuzzy model.The experiment result showed that the(T-S) fuzzy model can accurately reflect relation of output and input of the controlled system,and it showed that the(T-S) fuzzy model can be used to model and simulate for nonlinear control system too,which is a powerful tool of communication between modern control theory and nonlinear control system.
