Industrial load torque generation for electric machines using fuzzy voltage control strategy of DC machine field winding

This paper proposes a fuzzy control system that allows simulating experimental industrial loads coupled to electric machines rotor shaft. The main focus of the application relies on the improvement of a test bench that enables experimental essays before inserting the studied electric machine in the industrial process. In this paper, a direct current generator is coupled to a three-phase induction motor rotor shaft. The imposed load torque is generated by controlling the field winding supply voltage using PWM techniques. Experimental results are presented in order to analyze and validate the proposed system performance. Comparative analysis with conventional PID controller is also considered in this paper.
