Finite Control Set (FCS) Model Predictive Direct Current Control strategy with Constraints applying to drive Three-Phase Induction Motor

Abstract

In this, work the Finite Control Set (FCS) Model Predictive Current Control strategy with Constraints, is applied to drive Three-phase Induction Motor using the well-known field-oriented control. As a modern algorithm approach of control, this type of algorithm decides the suitable switching combination that brings the error between reference command currents and the predicated currents, as low as can, according to the process of optimization. The suggested algorithm simulates constraints of maximum allowable current and the accepted deviation between the reference and actual currents. The new constraints result in an improvement in system performance (contained), and with the predefined error. This can be applied by avoiding the switching state that exceeds the limited values. The additional constraints are more suitable for loads that need distortion in harmonic as little as possible and offer protection from maximum allowable currents.
