Dynamic Surface Control of the Axial-Flux Permanent Magnet Motor with Speed Sensorless Algorithm

EasyChair Preprint 5215

Abstract

The permanent synchronous motor drive system incorporates magnetic bearings to perform speed control and balance rotor control between the two stators. 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.
