Direct Power Control of BDFRG Based on Novel Integral Sliding Mode Control

Introduction: To address issues such as strong coupling and weak anti-interference capability in Brushless Doubly-Fed Reluctance Generators, this paper proposes a direct power control strategy using a novel integral sliding mode. Method: Firstly, by studying the relationship between the voltage on the stator control winding side and the active and reactive power on the power winding side, a direct power control model is derived, achieving decoupling control of active and reactive power. Results: Then, to solve the chattering problem, this paper proposes a novel integral sliding mode controller with a smoother function, improving the system's approach speed in the reaching phase and its precision in the sliding phase. Conclusion: Finally, through simulations and hardware-in-the-loop experiments, a comparison with traditional sliding mode control verifies the correctness of the derived model and the effectiveness of the proposed control strategy.
