Abstract

A Direct Torque Control scheme which regulates the flux and the electromagnetic torque of an induction motor (IM) is presented in this paper. A Cascade Asymmetric Multilevel Converter (CAMC) drives the IM in 7-level mode using a new voltage value for the flying capacitors. An integrated control scheme based on the Finite-ControlSet Model Predictive Control (FCS-MPC) approach undertakes the solution as a unique multi-objective control problem. The algorithm directly selects the switching states according to a rule of optimization and avoiding the use of modulators and nested controllers. Keywords   ,, .
