Enhanced simplified control algorithm for surface-mounted permanent magnet synchronous motors with sinusoidal excitation

In this paper it is proposed an enhanced simplified control system with good dynamical performances for surface-mounted permanent magnet synchronous motors with sinusoidal current control (BLAC), in that to determine the rotor position respectively the speed are used two Hall sensors. The concept of the proposed control system is a speed closed loop. The motor speed is controlled by the voltage amplitude and advance angle of the voltage relative to the vector of rotor permanent magnet flux, while the voltage frequency matches the actual speed of the motor. The voltage amplitude and the advance angle of the voltage are implemented using two tables and taking into account the "dq" model in rotor coordinates of surface-mounted permanent magnet synchronous motors with sinusoidal current control (BLAC).
