含扩展状态观测器的双馈风机事件触发滑模控制（撤销发表）

提出一种基于事件触发滑模控制(SMC)的双馈风机(DFIG)直接功率控制方法。传统的控制方法需要控制信号执行元件不断更新由计算单元传输的控制信号，而这种控制信号执行方式较为冗余且需要额外的通信和执行成本。事件触发控制原理能够决策所执行控制信号的最佳更新时间节点，并在保证控制效果的同时减少计算单元与执行单元之间的通信。将事件触发控制的原理与SMC结合起来，并用于DFIG的直接功率控制中。同时，设计了一种让系统具有主动抗干扰能力的扩展状态观测器。采用Lyapunov函数法验证了该控制系统的渐近稳定性。最后通过试验算例，验证了所提方法的有效性。

Event-Triggered Sliding Mode Control for DFIG Based on Extended State Observer (Retracted)

A direct power control method for the doubly fed induction generator (DFIG) is proposed based on event triggered sliding mode control (SMC). With conventional control approaches, the control execution units need to keep updating the control signal sent from the control center, which requires greater communication resources as well as computation efforts. With the event triggered mechanism, the optimal time slots for control signal update can be determined with the predefined event triggered condition and the requirement on communication between the computation and control execution units is reduced. The event triggered control theory and the SMC are combined, and applied to the direct power control of DFIG. Meanwhile, an extended state observer is designed to enhance the disturbance rejection ability of the system. The Lyapunov function is applied to validate the asymptotic stability of the control system. Experimental case study is conducted to evaluate the performance of the proposed method.
