本文提出了一种基于扰动观测的非线性自适应控制的鲁棒最大功率点跟踪（MPPT）控制方案，用于基于并网永磁同步发电机的风力发电机（PMSG-WT）。在所提出的控制方案中，PMSG-WT 的系统非线性、参数不确定性和外部扰动被表示为集总扰动项，由高增益扰动观测器估计。利用集总扰动的估计来补偿实际扰动，并进一步实现原始非线性系统的自适应反馈线性化控制，而不需要详细的系统模型和全状态测量。通过仿真研究和实验测试验证了所提出的控制方案的有效性。结果表明，与传统矢量控制器和标准反馈线性化控制器相比，所提出的控制策略提供了更高的功率转换效率，并且具有更好的动态性能和对参数不确定性和外部干扰的鲁棒性。 (C) 2018 Elsevier Ltd. 保留所有权利。
This paper presents a robust maximum power point tracking (MPPT) control scheme for a grid connected permanent magnet synchronous generator based wind turbine (PMSG-WT) using perturbation observation based nonlinear adaptive control. In the proposed control scheme, system nonlinearities, parameter uncertainties, and external disturbances of the PMSG-WT are represented as a lumped perturbation term, which is estimated by a high-gain perturbation observer. The estimate of the lumped perturbation is employed to compensate the actual perturbation and further achieve adaptive feedback linearizing control of the original nonlinear system, without requiring the detailed system model and full state measurements. The effectiveness of the proposed control scheme is verified through both simulation studies and experimental tests. The results show that, compared with the conventional vector controller and the standard feedback linearizing controller, the proposed control strategy provides higher power conversion efficiency and has better dynamic performances and robustness against parameter uncertainties and external disturbances.
