Abstract

This paper deals with an instantaneous feedback controlled inverter using sliding mode control. The theoretical contribution of this paper is that a common state-space-based sliding surface design method is extended for follow-up control. Starting from the basic theory of sliding mode control, the trajectory of the error signal is modelled. The practical contribution of this paper is the relationship between the trajectory of the error signal and the Total Harmonic Distortion (THD) of the output voltage signal. The conditions of the sliding mode control using an Uninterruptible Power Supply (UPS) are discussed. A rectifier as a non-linear load is simulated. Experimentally validated simulation results are presented.
