The intelligent fuzzy controller with dynamic integral term

This paper describes an intelligent fuzzy controller, with which the dynamic integral term is used according to the state of error and error change. This way improves the performance of fuzzy controller and overcome the overshoot of system response effectively. The controller works like an operator of system. When the output response tends to the given value, the integral terms come out of the system control; but when response leave off the given value, to add it to the control signal. Simulation results demonstrated that better control performance could be achieved in comparison with the standard fuzzy controller
