Abstract :

Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent. This controller is used in a double loop structure including an inner current loop and outer voltage loop. A case study has been simulated in SIMULINK to demonstrate the advantages of ADRC in control of inverters over PI controller. Simulation results demonstrate that load changes have no impact on performance of this control method and it is not sensitive to any uncertainty in parameters of the inverter.
