%X A novel model of inner-feed chopper cascade variable speed drive system using the state-space averaging method is proposed in this paper. The dual closed loop control strategy is then presented based on the model. The control circuits for realizing the control strategy are also investigated. Finally, a drive test is carried out, and the experiment results indicate the feasibility of the model and control strategy. Based on the control strategy, several devices with remarkable energy-saving effect are running well in the industry field. They exhibit excellent performance such as reliable DC-current protection ability, good dynamic response and static precision.
