ANN based voltage control for 3Ø SVM inverter fed induction machinedrives

This paper presents an efficient implementation scheme for the ANNbased voltage control of an induction motor incorporating space vector pulse width modulation (SVM). The data of a neural network is trained to estimate the voltage at different conditions. Voltage control is required to regulate the output voltage of the inverter. Space vector modulation (SVM) is an algorithm for the control of pulse width modulation (PWM). SVM gives better harmonic response and higher efficiency compared to PWM techniques. For non-linear loads, closed loop is achieved using a neural network controller. It is observed that the neural network controlled drive system has better dynamic performance.
