Induction motor drives for variable speed have many common industrial applications. An application of Artificial Neural Network (ANN) and genetic algorithms on vector control are carried out using space vector pulse width modulation in this study. Proportional plus derivative (PI) controller is used to control speed of induction motor. In this study, optimization of PI coefficients in vector control is carried out by ANN-Genetic. These controllers are applied to drive system with 0.55 kW induction motor. A Digital Signal Processor Controller (dsPIC30F6010) was used to carry out control applications. It is suitable to control induction motor as a soft starter and speed adjustment in compressors, blowers, fans, pumps and many other applications.]]>Betin, F. and D.
