In this work, the predictive model control will be applied to both back-to-back converter stages. Predictive power control and predictive torque control are applied respectively on the rectifier and the inverter which fed the motor. MPC evaluates the control variables in a cost-function to ...
The aim of this work is to give an accurate high frequency model of a complete AC PWM drive, starting from the transformer of the main power source, to the electrical motor. The proposed model allows to analyse the effects of the high dV/dt applied by the PWM inverter on the overvoltage...
weighting factors are used to set the relative importance of these objectives. However, selection of these weighting factors in predictive control of electric drives and
Self Tuned NFC and Adaptive Hysteresis Based DTC Scheme for IM Drive. The concept of field oriented control scheme brought the revolutionary change in industrial drives. Due to the high initial and running costs of the DC machines, the trend shifted from DC to AC motor drives to obtain high ...
