Control of Dual Rotor Induction Motor

Vector control characteristics of dual rotor induction machines driven by a single inverter are presented. This paper studies a simple control method which could be applied to the dual rotor induction machine, taking into consideration that the system applied to electric vehicles must operate along a cornering path as well as a straight path. The vector control method used in this paper shows generally good performance in cases where the speed command and the loads given to dual rotors are changed. Hence the method should be considered for application to dual rotor induction motors for electric vehicles. A proposed speed control scheme is simulated to illustrate the validity and effectiveness of the approach.
