Sliding Mode Repetitive Control of PWM Voltage Source Inverter

This paper proposes a hybrid sliding mode repetitive control scheme that combines both the features of the sliding mode control and the repetitive control to achieve excellent transient and steady-state system performances in voltage source inverters. The principle of equivalent control is adopted to integrate the two methodologies and to facilitate the design and analysis of the proposed scheme. A specific low pass filter is also introduced to improve the transient response of the regulation. Experimental results show that fast dynamical responses are achieved through the sliding mode control, while low harmonic distortions are achieved through the repetitive control.
