SLIDING MODE WITH PI CONTROL STRATEGY OF FLYING CAPACITOR MULTILEVEL INVERTER

Abstract
Abstract - In this paper, a sliding mode control (SMC) is applied to the current loop of a Flying Capacitor Multilevel Inverter (FCMI), with a PI (Proportional Integral) controller required for the voltage loop. SMC is applied to ensure high output current stability and performance against large parameter variations and external disturbances. The system (FCMI) is powered by a photovoltaic generator (GPV) under conditions of unstable solar irradiance and variable load in order to validate the performance of this control method. This control strategy is easy to implement and ensures stability and good dynamic response under a wide range of operating conditions. The simulation results prove the robustness and accuracy of the proposed technique, in comparison to conventional methods. Keywords - Flying Capacitor Inverter, Sliding Mode Control, PI Control.
