Sensorless Dead-Beat Control of Three-Phase Inverter for Stand-Alone Distributed Generation Systems

Abstract

Three-phase inverters for standalone distributed generation systems (DG) control techniques has high importance in applications where a high quality power is required. Indeed, the reliability, efficiency while offering low cost and size of such systems is the bottle-neck issue and is becoming a heated research topic. This paper adresses a sensorless dead-beat control scheme of three-phase converter for a distributed generation system in a standalone operation mode. The proposed control strategy consists of two control loops. The outer one, which is used for the control of the output voltage, is based on a PI controller and the inner loop that is used for the control of the output current is based on a Deadbeat Predictive (DB) controller. Moreover, unlike other control methods, the proposed control scheme requires only current sensor. To validate the performances of the proposed control approach (i.e., fast transient response, zero steady-state error, and low THD), simulation tests under various types of loads such as balanced load, and nonlinear load in MATLAB/Simulink are presented.
