A Method of Speed Sensorless Vector Control Parallel -Connected Dual Induction Motors Fed by One Inverter in a Rotor Flux Feedback Control

A purpose of this paper is to present the speed- sensorless vector method of parallel-connected dual induction motors fed by one inverter. This system may be unstable when the ratings of each induction motor are different and an extremely unbalanced load for both motors is added. Then we suggest a control method that the system can be stable in this condition. According to this method, the rotor flux is directly controlled to be constant by a rotor flux feedback control though it isn't controlled in an ordinary system.
