Abstract

This paper investigates the importance of controller’s energy optimization opportunity of a Double-Star Induction Motor (DSIM). We introduce a concept of a nonlinear functions minimization using tow topologies namely energy model based optimal flux using Euler equation and a minimum energy consumption using particle swarm methodology (PSO). In this study, the rotor flux level in a machine has been considered to be adjusted to give minimum energy for a given load of the motor in dynamic regime. Good results are obtained with PSO in dynamic regime, compared to Euler equation based on analytic solution.
