dSPACE implementation of fuzzy logic based vector control of induction motor

Vector control of induction motor is an efficient approach to control the speed of induction motor used for industrial drives. Although the vector control is very popular method but there lies difficulty in obtaining an accurate model of induction motor (IM) owing to the variation of induction motor parameters, such as resistance, inductance and time constant. Therefore, to cope up with this uncertainty in the model we used a fuzzy logic based vector control approach to speed control of an induction motor. The focus of the paper is to analyze the real-time implementation issued for realizing a vector control in a laboratory set up of induction motor using dSPACE 1104. This fuzzy logic based vector control scheme has been successfully implemented on a 3 hp induction motor drive in the laboratory and the performances of this controller has been checked with a PID control strategy.
