I-p-d Type Fuzzy Control for Dc Motor

In this paper we propose a parallel structure of I-P-D (Integral minus Proportional minus Derivative) type fuzzy controller based on the conventional PID control theory, used to control the speed of DC motor. The conventional PID controller exhibit poor performance when applied to DC motor, it fails to perform satisfactory under parameter variation or load changes. The parallel I-P-D type fuzzy controller are designed according to fuzzy rules so that system becomes fundamentally robust and the system shows better performance in transient state as well as steady state. The performance of the proposed control algorithm has been compared with the classical PID controllers on the basis of different performance indices. So by integrating the I-P-D type fuzzy controller to the DC motor were able to correct the error made by the DC motor and control the speed or position of the motor to the desired point or speed.
