We present an unexampled reset integrator control design based on the Clegg integrator system. Using an appropriate mathematical model of our Clegg integrator controller, stability proof of the closed-loop system applied to the vibration control problem of a second-order system is shown without invoking hybrid system theory. Furthermore, we illustrate the applicability of our controller, from t...

This paper offers a detailed analysis as well tuning and discretization approach of the presented frequency-fixed dual second order generalized integrator based phase-locked loop (FFDSOGI-PLL) for three-phase power systems. The method combines different single- PLL approaches by ensuring high phase- frequency tracking properties. comparison with standard frequency-variable DSOGI-PLL three recen...

The three-phase four-wire VSCs voltage source converters are used to connect sustainable sources the distribution system where loads predominantly single-phase. with unbalanced neutral has unwanted negative and zero sequence components. In this condition synchronism between VSC electrical grid that is done using PLL (Phase Locked Loop) affected. SRF-PLL (Synchronous Reference Frame-PLL) popular...
