| Abstract: | This paper presents a novel full-digital current strategy for a servo system with a perma-nent magnet synchronous motor,in which a proportional current regulator with regularlysampled PWM is used. Current feedforward compensation and variable proportional gaincontrol techniques are used to improve the performance of the current regulator. Digital sim-ulation and experimental results are given. |
