The process of cotton producing is a very complicated process. There are many characteristics, such as non-linear and large delay. As a result, it is very difficult to build a system model. We can say that conventional control is valid to effective control. In this paper, the fuzzy controller is used in the control system to deal with those problems. Under using of the fuzzy control technique, sensor technique, FIX technique and imaging technique, we will gain the better intelligence control, increasing the accuracy and improving the stability and robustness of the system. As a result, the ginner can be free and save labor and excellent results are obtained.
