直驱型永磁同步风力发电机组中混沌运动的反步自适应控制

摘要

In this paper, a mathematical model of direct-driven permanent magnet synchronous generator( D-PMSG) is derived with taking into account the parametric uncertainty and the disturbance of wind. And also the chaotic property under the condition of certain system parameters and a certain operation is verified. Furthermore, the adaptive backstepping approach is designed to compensate the parametric uncertainty and wind disturbance. The simulation results show that the proposed controller for D-PMSG is effective and robust against the parametric uncertainty and the wind disturbance.%以直驱型永磁同步风力发电机为研究对象,推导了发电机在参数不确定以及风速扰动情况下的数学模型,验证了系统在某些参数及工作条件下会呈现出混沌属性.并提出了直驱型永磁同步风力发电机混沌运动下的基于反步自适应控制算法,并对其进行了仿真,仿真结果表明,所提出的算法对于具有参数不确定以及风速干扰的直驱型风力发电系统具有较好的鲁棒性.
