摘　　要：在分析了船舶双馈轴带发电系统的结构特点之后,建立了同步旋转坐标系下双馈轴带发电机的数学模型。在此基础上,提出了一种线性自抗扰并车控制方法。采用扩张状态观测器对转子电流状态方程中的不确定项进行观测并加以补偿,提高了系统的跟踪性能。为了实现无冲击并车,根据自抗扰控制的计算原理,设计了无扰切换的具体实施方法。仿真和实验结果表明,与PI控制相比,该控制方法超调量小,响应速度快,抗扰能力强,更适合应用在对可靠性要求较高的船舶领域。By analyzing the structural characteristic of ship shaft doubly fed induction generator （DFIG） system, the mathematical mode of ship shaft DFIG was buih in the synchronous rotating frame. A synchronization control strategy was proposed based on linear active disturbance rejection control （LADRC）. Extended state observer （ESO） was used to observe and compensate the unknown items in the rotor current state equations, which improves the system tracking performance. Based on the principle of LADRC algorithm, the specific implementation method of bumpless switching was designed for the successful synchronization. Simulation and experiment results show that, compare with PI control, the proposed control method has smaller overshoot, faster response speed and stronger anti-disturbance capacity. It is suitable for the requirement of high reliability in the ship field.
