Linear Active Disturbance Rejection Control with Fuzzy Logic in DC Bus Voltage for Wind Power System

In the field of distributed energy, wind power generation technology will continue to be an important force to adjust the energy structure for a long time in the future. In order to improve the fault ride through (FRT) capability of the wind power system based on a permanent magnet synchronous generator (WPS-PMSG), a linear active disturbance rejection controller with fuzzy logic (LADRCFL) is proposed for grid-connection control. In this strategy, the fuzzy logic is used to realize the self-optimization of control parameters. In addition, part of the model information was written into the linear extend state observer (LESO) matrix based on mathematical model analysis, so as to enables the observer to estimate the speed and accuracy of the system to a higher level. A digital simulation platform has been developed in this paper to replicate the wind power system utilizing a permanent magnet synchronous generator.
