Kurzfassung englisch:
Finite control set model predictive control (FCSMPC)
has been proven to be a powerful control strategy in power
electronics with very high dynamic performance compared to
carrier-based pulse width modulation (PWM) approaches while
avoiding unnecessarily high switching frequencies that would
increase switching losses. However, the limited time resolution
often leads to poor steady-state performance and can only
be overcome by increasing the sampling rate, which would
involve an infeasibly high computational demand. This paper
presents a predictive pulse pattern control (PPPC) strategy for
a synchronous multiphase buck converter (SMPB) that achieves
both objectives yielding in high performance for transient and
steady-state operating conditions with a feasible computational
demand. At every time step, a pulse pattern with minimal
switching effort is selected whose switching instants are obtained
by minimizing an objective function yielding in high tracking
accuracy. Simulation results demonstrate the potential of the
proposed control strategy to outperform state-of-the art control
