摘　　要：针对永磁直驱风力发电机的特点,本文采用一种基于低通滤波补偿积分器的无位置传感器零d轴电流控制技术.在论述该控制技术实现原理的基础上,深入分析了低通滤波补偿积分器特点,最后通过仿真和小功率直驱型永磁风力发电实验平台,验证了其有效性.结果表明,该方法具有较好的稳态与转矩动态响应性能,且工程实现较为简单.With the characteristics of direct-drive permanent magnet synchronous generators （PMSG）,a sensorless zero d-axis current control（ZDAC） method based on low pass filter compensation integrator （LPFCI） is proposed. Its implementation principle is introduced in detail. Furthermore, LPFCI is discussed in depth. FinaLly, simulation and experiment results on a low power permanent magnet wind generation platform indicate the feasibility of the method. Results also show its excellent steady and torque dynamic response performance as well as easy implementation.
