Abstract

This paper proposes an approach to control the current amplitude and phase simultaneously. To do this, sliding mode control and adaptive parameter estimation are applied to the current control of a single-phase PWM inverter with unknown R-L series load. The load parameters, R and L, are estimated by using the recursive least square method and these parameters are used to adjust the feedback gains of control input. The inverter system is modelled in a second-order system by treating load current variation caused by inductive component as a disturbance. A DSP-based (TMS320C30) PWM inverter controller is implemented to verify the effectiveness of the proposed control scheme. Simulation and experiment based on the second-order model are done and the results show good dynamic response and low THD.
