Abstract

Generally, PID control has been used for Torque, Speed control and stability, and the same character of DC Motor has been researched on actively for the stable driving and the correct speed control. This study shows the possibility of the high efficient speed control with fuzzy controller using individual moving mean method for the strong control and the stable speed control by research. The gains of PID controllers will have the good control response characters if they will be selected properly. But the DC series winding motor have the non-linear control character in the real system, it is difficult to get the very good control response. In order to fet rid of this problem, this paper suggested the current controller of the electric forklift.
