Electric spring control based on intelligent controller and cascade second-order generalized integrator phase locked loop

Sigmoidal and Gaussian functions based neural neuron technique for grid interactive solar energy system enabling power quality improvement

“…The generalised integrator‐based controllers are utilised to generate signals for the hysteresis control, which is utilised to evaluate on–off pulses for interfaced VSC switches. A cascade second‐order generalised integrator (SOGI)‐based phase locked loop (PLL) control is exhibited in [11]. A PLL based on SOGI is exhibited in [12].…”
