This paper proposes a novel control strategy for stand-alone doubly fed induction generator (DFIG)-based wind energy systems by integrating fractional-order operators into a fuzzy logic control (FLC) framework. Conventional FLC approaches typically use integer-order operators, which may restrict the system's adaptability and dynamic performance. In this work, the standard integral and derivative components are replaced with fractional-order counterparts, resulting in a fractional-order fuzzy logic (FOFL) controller with a more flexible and tunable control architecture. This enhancement enables finer adjustment of the system response and improved robustness against external disturbances. The FOFL controller is applied within a direct voltage control (DVC) scheme to control the stator voltage and frequency. The performance of the proposed FOFL-DVC strategy is validated through simulation in MATLAB/Simulink and real-time experimental testing using a dSPACE-1104 platform. Results demonstrate that the FOFL-DVC strategy achieves high performance under both steady-state and transient conditions, ensuring stable operation under various wind speed and load disturbance.
本文提出了一种新颖的控制策略，通过将分数阶算子集成到模糊逻辑控制（FLC）框架中，用于基于独立双馈感应发电机（DFIG）的风能系统。传统的FLC方法通常使用整数阶算子，这可能会限制系统的适应性和动态性能。在这项工作中，标准的积分和微分分量被分数阶对应物取代，从而产生了一种具有更灵活和可调节控制架构的分数阶模糊逻辑（FOFL）控制器。这种改进使得能够对系统响应进行更精细的调整，并提高对外部干扰的鲁棒性。FOFL控制器应用于直接电压控制（DVC）方案中，以控制定子电压和频率。通过在MATLAB/Simulink中进行仿真以及使用dSPACE-1104平台进行实时实验测试，验证了所提出的FOFL-DVC策略的性能。结果表明，FOFL-DVC策略在稳态和瞬态条件下均实现了高性能，确保了在各种风速和负载干扰下的稳定运行。
