A novel control technique for sensorless vector control operation of double inverter fed wound rotor induction motor is presented. Two current controllers control the stator side currents based on vector control algorithm. Another V/f type flux and frequency controller controls the rotor side frequency directly. A novel frequency command profile for the rotor side controller is suggested to make this sensorless drive operation reliable and less dependent on motor parameters at any rotor speed…

Sensorless double-inverter-fed wound-rotor induction-Machine drive
Novel frequency profiles are proposed, which ensure that the frequency on either side never drops below a minimum value, resulting in simple sensorless control and the estimation of flux can be simply and reliably carried out by integration of voltage.
Single external source control of doubly-fed induction machine using dual inverter
The proposed drive system and a control method for a double inverter fed wound machine, where the stator and the rotor are fed by two variable frequency inverters, can improve the operating area and the efficiency because the rotor side inverter allows an additional degree of freedom in control.
