This paper proposes a fully digital control scheme for high-performance induction servo drives. A software current vector control in synchronous rotating reference frame with feedforward back emf compensation has been developed for the current-regulated PWM inverters. A dual-DSP based digital controller using the TMS 320C14 and TMS 320C50 from the Texas Instruments has been employed to realize the proposed software servo control scheme. Experimental results show the proposed control scheme can achieve robust servo requirements and at the same time maintain a fast current response with small current ripples.
