Abstract
This paper explores the combination of Model Predictive Control (MPC) and the Sphere Decoding Algorithm (SDA) to control a three-phase, variable-speed induction motor drive through a three-level inverter. It builds upon previous work in which a framework to simplify the integer optimization problem using Laguerre Polynomials (LPs) was introduced. The objective is to obtain a much faster convergence of the algorithm through a reduction in the dimensionality of the optimization problem. Specifically, this work explores different parametric selections to better understand their effects on the performance of the algorithm.
