The proposed controller is mainly divided into a feed-forward and a feedback compensators. In order to obtain a simple controller, the former gives a steady-state control input designed using a nominal plant gain, and the latter...
Aiming at the problem that the single position closed loop PID controller cannot meet the specifications of the motion control of the great inertia system with backlash, a double position closed loop fuzzy PID controller is proposed in this paper. Compared with the general fuzzy logic controller and PID controller, the results show that this control method can greatly improve the system's control...
