In this study, a new sensorless master slave direct torque control of permanent magnet synchronous motors based on speed MRAS observer is proposed for a multi-machine system in electric vehicle. The speeds of both motors are estimated by using Model Reference Adaptive System (MRAS) scheme. A classical system with multi-inverter and multi-machine comprises a three-phase inverter for each machine to be controlled. Another approach consists in using only one three-phase inverter to supply several permanent magnet synchronous machines. A new DTC algorithm is used for the control of bi-machine traction system. Simulation results in MATLAB/SIMULINK indicated that the new DTC algorithm is well adapted for the synchronism of this system over a wide range of operations.
