Nonlinear Integral Backstepping Control of Machine Side Converter PMSG Wind Turbine Conversion System During Grid Faults

To solve the problem of balanced power grid voltage faults in Wind Turbine Conversion Systems (WTCS) based on Permanent Magnetic Synchronous Generator (PMSG), an advanced method solution based on Machine Side Converter Control (MSC) using the Integrated Back-Stepping Control (IBSC) is proposed in this paper. This nonlinear IBSC technique effectively addresses the harmonics of the stator current in the classical Proportional Integral control (PI) and enhances the dynamic performance of the MSC such as the DC link voltage controls during grid faults. The suggested IBSC method and its efficacy in comparison to the traditional PI method are demonstrated by time-domain simulation tests conducted on a WTCS-driven PMSG utilizing MATLAB/Simulink.
