Abstract

In this research, we aim to construct an unique sliding mode control time-varying switching surface that allows us to accurately synchronize fractional-order permanent magnet synchronous generator (FOPMSG) system at any arbitrary pre-specified time. With regard to the suggest methodology, the top limit of the synchronization time is entirely independent and depends entirely on the design parameters for the switching surface and control system.
The major goal of modeling non-linear PMSG fractional-order control is to improve the convergence rate which, compared to integer-order systems, is effectively superior. Moreover, resilience against existing uncertainties and external
disruptions is achieved by removing the reaching phase within the proposed synchronization method. Furthermore, the Lyapunov stability theory is based on enough circumstances, which assures synchronization with the FOPMSG system at the pre-specified time, through the construction of a Lyapunov functional and SMC with switching surface. Finally, numerical examples and simulations to compare SMC scenarios highlight the usefulness of theoretical conclusions.
