Abstract：The dual winding induction generator system adopts the flux-oriented control strategy to adjust the active current and the reactive current separately, so as to obtain stable control of the DC voltage at both ends of the control winding and the power winding. However, the control strategy is relatively complicated, and multiple regulators bring difficulties in the design of the controller, which restricts the further development and application of the dual winding induction generator system. Therefore, a deadbeat predictive current control strategy for the dual-winding induction generator system is proposed, and a predictive model of the generator system is established. In a control cycle, with the goal of eliminating the error of the controlled quantity, the required control quantity is directly calculated. The current error caused by the model parameter mismatch is analyzed, and error compensation is made for the control strategy. The proposed deadbeat predictive current control strategy avoids the cumbersome adjustment process of regulator parameters, has excellent control performance, and achieves error-free current tracking. The prototype simulation and experimental results verify the correctness and feasibility of the predictive current control of the dual winding induction generator system.
