    This article presents an overview of the problem of identifying linear and nonlinear systems (Wiener type) operating in open loop. There are several algorithms that solve this problem, among them are the subspace methods (MOESP and N4SID). In order to evaluate the performance of the MOESP and N4SID methods, a simulated example is presented to compare the performance of these algorithms.

    Neste artigo é apresentada uma visão geral sobre o problema da identificação de sistemas lineares e não lineares (tipo Wiener) operando em malha aberta. Existem diversos algoritmos que solucionam este problema, entre eles encontram-se os métodos por subespaços (MOESP e N4SID). Com o objetivo de avaliar o desempenho dos métodos MOESP e N4SID, um exemplo simulado é apresentado para comparar o desempenho destes algoritmos.
