摘要:

针对永磁直驱风力发电系统实现最大风能捕获的问题,提出一种高阶非奇异终端滑模控制策略.根据永磁直驱风力发电系统的非线性模型,基于最佳转矩跟踪的最大功率点跟踪(maximum power point tracking)方法,将高阶非奇异终端滑模控制应用于永磁同步发电机(permanent magnet synchronous generator)设计转矩控制器和电流控制器,实现永磁直驱风力发电系统的无风速传感器最大功率点的快速跟踪和稳定控制.仿真结果验证了所提出的控制方案的有效性.

Abstract:

A high-order non-singular terminal sliding mode control strategy is proposed to address the issue of achieving maximum wind energy capture in permanent magnet direct drive wind power generation systems. Based on the nonlinear model of the permanent magnet direct drive wind power generation system, a maximum power point tracking method based on optimal torque tracking is proposed, Applying high-order non-singular terminal sliding mode control to the design of torque controller and current controller for permanent magnet synchronous generator (PMSG), achieving fast tracking and stable control of the maximum power point of the permanent magnet direct drive wind power generation system without wind speed sensors. Simulation results verify the effectiveness of the proposed control scheme
