“…En la literatura existen diversos algoritmos de control implementado en los convertidores electrónicos de potencia para lograr el seguimiento o regulación del voltaje de salida del convertidor al voltaje deseado. Existen trabajos basados en el enfoque clásico del control PID como se cita en (Ramesh et al, 2014;Anak Ajot et al, 2017;Cherati et al, 2011). Otros, como en (Bagheri and Komurcugil, 2022;Guo et al, 2019) hacen uso de técnicas de control no lineal como los modos deslizantes empleando estrategias de reducción de chattering para evitar el efecto de ruido que provocaría en sistemas eléctricos.…”

The following paper presents the modeling and design of a backstepping controller based on saturation functions for a single-phase off-grid inverter system. The proposed controller consists of an algorithm that modifies the controller gains as a function of the error, which is intended to avoid the windup effect and to adapt to changes in system parameters, such as inverter load. The objective of the bakstepping controller acting on the system is to reduce the tracking error and improve the voltage quality at the inverter output by reducing the total harmonic distortion. The results of the backstepping controller with saturated gains are compared against backstepping with constant gains in order to test its performance improvement.

“…The main problem with hysteresis current control is its variable switching frequency that roots high switching losses and higher order harmonics in the load current, thereby increasing ripple current [18], [19]. The PI current controller has the problems of steady-state magnitude error, phase lag and limited disturbance rejection capability in controlling the load current [20], [21]. The current control methods are analyzed with the level of load current THD, reference current tracking capability and unbalanced load conditions.…”

A detailed model and analysis of a five-level cascaded H-bridge (CHB) multilevel inverter with different current control methods are presented. Simulation models of the CHB inverter with hysteresis current controller, PI current controller using SPWM technique and predictive current controller have been built to demonstrate the CHB inverter system performance with regard to load current THD and reference current tracking. In controlling the load current, the hysteresis and the PI current controllers have the problem of current ripple and phase lag, respectively. The proposed predictive current control method effectively addresses these issues. The current control methods are analyzed for varying reference current and unbalanced load conditions. The simulation results are observed and analyzed using the MATLAB Simulink software to validate the current control methods.

The use of renewable energy sources is highly demand in electricity market nowadays. The incorporation of renewable energy sources with the utility grid has becoming a challenging task in power system as it arises several control issues such as grid stability, power quality control, loads sharing and others. This paper presents current control methods namely Hysteresis controller and Proportional-Integral controller used to interface of single-phase grid connected inverter with nonlinear load. The impact of nonlinear load on grid current is analysed by measuring the performance of total current harmonics distortion (THDi) level in MATLAB TM Simulink software environment.
