摘要

提出了一种基于LQ最优控制的RST控制器，用于通过背靠背变流器与电网连接的风能转换系统(WECS)的最大功率跟踪。采用输入输出离散WECS模型实现了输入输出最优控制方法。性能准则包括两项:第一项涉及最大功率跟踪，另一项涉及机械疲劳载荷(控制输入)最小化。所得到的模拟结果表明，所考虑的控制和可变风廓线的转换系统具有足够的动态性。

Optimal control based RST controller for maximum power point tracking of wind energy conversion system

This paper presents an LQ optimal control based RST controller for maximum power tracking in a wind energy conversion system (WECS) connected to the electrical grid through a back-to-back converter. Input-output discrete WECS model has been used to implement the input-output optimal control approach. The performance criterion has two terms: the first one is involved for maximum power tracking and the other one for the mechanical fatigue loading (control input) minimization. The obtained simulation results with the considered control and a variable wind profile show an adequate dynamic of the considered conversion system.
