Metodos Numericos NA Resolucao Do Modelo de Uma Eletrovalvula de Controle (Numerical Methods in the Resolution of Control Electrovalve Model)

摘要

This work shows the numerical method application in the resolution of the model of transistors in an electrovalve employed in the satellite attitude control. The primary support method is the curve approximation through third degree spline polynomials, used to approximate the curve characteristics of ferromagnetic materials. Two methods for localization of zero functions are used, the Newton-Raphson and the Regula Falsi. For the last, through a system of differential equations derived from the model, the predictor-corrector and the Runge-Kutta are applied, this final stage initiates the former. Also shown are some typical results obtained with this model.
