The purpose of this paper is to develop a nonlinear and multivariable model, using the step response in a industry didactic plant, which is used in the course of industrial process control at IFES - SERRA (ES). From the physical equations are determine the stationary behavior of the plant in any operation point. By using the step response, the dynamic characteristics of the plant is approximated by...
The approximate solution of systems governed by linear differential operators in two space dimensions is achieved by a new least-squares collocation technique using Patterson quadrature points and weights. Boundary conditions which are identicaly imposed on the approximate solution may be optimised, and the scheme may be used to rapidly predict feedforward control parameters. Boundary conditions which...
