Design of current control of fully integrated surface-mounted permanent magnet synchronous motor drive servo actuators

A stationary frame-based synchronous digital current control for a surface mounted permanent magnet synchronous motor (PMSM) drive of integrated servo actuators is considered. A two phase stator stationary coordinate frame realization synchronous current controller with the anti-windup is presented. A simple implementation of space vector PWM algorithms which provide continuous transition from sinusoidal PWM to six-step operation PWM mode is developed to enhance the current dynamic performance
