Simplified numerical solution of electromechanical systems by look-up tables

Abstract

In this paper, a lumped parameter model of electromechanical systems is developed and its solution is simplified by using look-up tables (13). The model is developed in two steps. First, a Simulink model of the electromechanical system is built using algebraic equations of the magnetic circuit which contains nonlinear effects. in the second step, the model is simplified using LT which replace the nonlinear effects. LT are created by the program developed in MATLAB environment. The simulation run-times of the simplified model is about 50% less than those of the first model while the accuracy of the solutions remains same. Experimental studies are evaluated on two different electromechanical systems to show the accuracy of the new model. Simulation results were compared with the experimental results and a good agreement is obtained between them.
