Voltage multiscalar control of induction machine supplied by current source converter

Control systems for the induction motor fed by current source converter based on a multiscalar models are presented in this paper. The topology of current source inverter is shown. Equations of multiscalar model of the induction motor are derived. The multiscalar model is the new approach to the control of induction motor based on DC-link current and rotor flux vector. The speed observer system is applied to receive sensorless drive. Properties of the sensorless control system are presented. The investigation carried out on experimental drive system confirms simulation results.
