To improve the efficiency of the wind power generation, this article proposes an active disturbance rejection controller (ADRC) based MPPT strategy, and establishes a LabVIEW FPGA platform based hardware-in-the-loop (HIL) test system. Firstly, the configuration, operation principle, mathematical model and maximum power point tracking (MPPT) control strategy of the wind power generation are analyzed. According to the angular speed tracking motion equation of the wind turbine, the ADRC based MPPT strategy is designed. Secondly, the real-time simulation model of wind speed, wind turbine and PMSG, as well as MPPT rapid control prototype (RCP) are developed by using PXI-FPGA architecture on the LabVIEW RT real-time operation platform. Then, by building a power converter and connecting it to the PXI-FPGA real-time operation platform, the HIL test system is established. Finally, the HIL real-time simulation tests are conducted with various wind speed conditions. The results not only prove the correctness of ADRC based MPPT strategy, but also demonstrate that the HIL system is an efficient tool for application in wind power generation development.
