Sensorless Control of a Slip Ring Induction Generator based on Rotor Current MRAS Observer

A sensorless control strategy of a slip ring induction generator supplying energy to an isolated load is presented. The position, needed for the vector control scheme, is estimated using an MRAS observer. The input to the observer is the rotor current both from direct measurements (reference model) and from stator voltage and current measurements (adaptive model). The scheme is validated in a six poles, 2.5 kW induction machine. Sub and super synchronous operation is allowed using a Scherbius scheme with two back-to-back PWM voltage source inverters. The generator is driven at variable speed by an AC drive. Results are presented for the speed/position estimation during steady state and transient conditions
