Abstract

In this article a proposal to solve two control problems from multiple point identification process frequency response of linear models, using an open loop step, is presented. The identified points are used, in one case a PID controller tuning, and the other application deals with transfer function modeling problem, both problems are stated as a nonlinear least squares unconstrained minimization problem. The optimization problem is solved with a simple genetic algorithm.
