Abstract-A new current control method based on the internal model principle in control theory is proposed. It introduces a sinusoidal internal model into the control system. It does not use any coordinate transformations. The method can be used for tracking an arbitrary number of harmonics: a dc component or fundamental frequency component signal. It is applied to a single-phase pulsewidth modulation inverter and active filter. The validity is confirmed by simulation and experimental results.

A new current control method based on the internal model principle in control theory is proposed. It uses a sinusoidal internal model, but it does not use any coordinate transformations. The method can be used for tracking an arbitrary number of harmonics, a DC component or a fundamental frequency component signal. It is applied to a single-phase PWM inverter and an active filter. Simulation and experimental results confirm the validity of the proposed method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
