dSPACE IFOC Fuzzy Logic Controller Implementation for Induction Motor Drive

In this paper we interest a real implementation using DS1104 controller board of indirect rotor flux oriented control (IRFOC) of an induction motor supplied by hysteresis current- controlled inverter. Simulation and Experimental results of a sensorless speed control using a PI Fuzzy speed controller are presented. The control loop of the motor speed, proposed in this paper, is provided by a PI controller based on fuzzy logic. The induction motor speed estimation proposed in this paper is based on simple relationships between voltage and current and easy to implement in real time.
