In this paper, a control without speed sensor with extended Kalman filter (EKF) for command a permanent magnet synchronous motor (PMSM) speed rotor position estimation is proposed. The direct torque control (DTC) technique for permanent magnet synchronous motor (PMSM) is receiving increasing attention due to the significant advantages of low dependence on motor parameters compared to other motor control techniques. The Kalman filter is an observer of linear and nonlinear systems and is based on stochastic intromission, in other words, noise. The PMSM is powered by an electronic power converter. Simulation tests performed for different operating conditions have confirmed the robustness of the whole system.
