摘要
针对一种变速变距风力发电机,提出了一种滑模变结构鲁棒控制方案.由于滑模变结构具有独特的优点,因此应用滑模变结构原理设计了滑模变结构控制器.通过分析可知,所设计的滑模变结构控制器不但可以控制风轮转速使之从风中获得最大功率,还可以控制浆距角调节的速度,进而通过浆距调节来使输出功率平稳.仿真实验结果表明所提出的控制方案是十分有效的,此控制系统具有良好的鲁棒性能.
A sliding model variable structure (SMVS) robust control scheme for a variable speed adjustable-pitch wind energy conversion system is presented.Because of the unique merit of SMVS,a controller is (designed) according to the SMVS theory.The designed controller regulates the turbine speed to extract (maximum) power from the wind and adjusts pith to obtain constant power.The simulation results show the (proposed) scheme is effective and has strong robust performances.
