A novel voltage-current dual-loop control scheme combined the advantages of sliding mode variable structure control and non-linear optimal control was presented, it uses the sliding-mode variable structure control as the voltage loop, takes the advantage of good robustness of variable structure control and its well adaptive to load stir to generate index current; and uses non-linear optimal predictive control as the current loop, which can eliminate the tracking error in one to several period, have the advantage of high response speed, good tracking precision etc, and is well suited to digital control system. The validity and advantage of the proposed control scheme are verified by simulation and experiment results.
