Model predictive resonant control of a three-phase voltage source converter with selective harmonic compensation

This paper develops and experimentally-validates a new model predictive control based design for grid-connected three phase voltage source converter. In particular, the operation of a three phase voltage source converter in the stationary frame is considered where signals that vary sinusoidally with a period determined by the grid frequency must be controlled. Hence the internal model principle is exploited to add terms that achieve zero steady-state tracking errors and the result termed model predictive resonance control (MPRC). A selective harmonic compensation controller, to operate in conjunction with the MPRC, is also designed to minimize the odd-order harmonics in the grid-side current caused by the grid-voltage harmonics. The results of an experimental validation of the final design are also given.
