The paper designed a system to perform adjusting motor speed sensorless based on measured current and voltage components. The elec-tromotive force (back-EMF) generated in the stator is estimated by a High-Gain observer. The angular position and velocity rotor is calculated through the α-β components of the back-EMF. The motor drive is built in a vector control structure based on the rotor flux. In which based on the Lyapunov stabilization function, the dynamic surface control method is used to calcu-late the axial position and speed controller of the motor. Simulation results show that the proposed controller and observer are fully capable of meeting the system control requirements.
