A nonlinear Real-Time Pulse-Pattern MPC Scheme for Power-Electronics Circuits Operating in the Microseconds Range

This work proposes a novel online switching time control scheme for power electronics applications. It is based on an accurate variable time integration scheme using numerical integrators, which in turn also allows to address almost arbitrary nonlinearities arising in practice. Two well-known effects, namely the blanking time and the magnetic saturation of inductors, are considered to demonstrate the possibilities and versatility of the proposed scheme. Real-Time capability is proven using an embedded processor-based control system controlling a power converter operating at a sampling time in the lower microseconds range.
