In this paper, a new sensorless Interior Permanent Magnet Synchronous Motor (IPMSM) drives method with Extended Kalman Filter (EKF) for speed, rotor position and load torque estimation is proposed. The Direct Torque Control (DTC) technique for PMSM is receiving increasing attention due to the important advantages of the low dependence on motor parameters when compared with other motor control t...

In this paper, aiming at the known or unknown uncertainties in permanent magnet linear synchronous motor (PMLSM) servo system, an intelligent backstepping terminal sliding mode control (IBTSMC) method is proposed for accurate position tracking of system. The designed controller makes use advantage theory to ensure fast convergence and robustness. Finally, stability analysis carried out by using...

In the industry, permanent magnet synchronous motors are one of most widely used and have superior performance compared to other types motors. The principal objective this paper is ameliorate PMSMs by implementing a robust non-linear backstepping control. first part deals with vector control mechanical sensors using PI controller. second part, we shed light on control, Lyapunov function, PMSM f...

This paper proposes an improved predictive position control (IPPC) method based on the disturbance observer (DOB) for linear synchronous motor (LSM) to enhance tracking accuracy and robustness against parameter mismatches load disturbance. A soft constraint containing difference between errors their exponential convergence trajectory is developed cost function improve accuracy. Moreover, IPPC e...
