We propose a novel framework for multistep predictive current control for induction machines and 3 Level-Neutral Point Clamped Inverter. To ensure low computational complexity. The multistep prediction horizon is implemented using a sphere decoding algorithm. The DC-link balancing is guaranteed by adding a linearized DC-link balancing term. In order to obtain high accuracy, the linearization is performed during the online stage of the framework. Since the system is not differentiable we furthermore define a linearization framework based on the weak derivative. The framework is verified by means of simulations.     «
