This work proposes methods to incorporate penalties on specific frequency components of the output signal into a Model Predictive Control (MPC) problem formulation. This is relevant for many control applications, in which the control objectives are specified in the time domain (e.g. tracking), as well as in the frequency domain to shape the output spectrum of the system. Focusing on a grid-connected converter system, the objective function of Finite Control Set MPC is augmented by spectral penalties to shape the harmonic spectrum of the converter current.
