Previous issue date: 2009-03-27 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The Predictive Controller has been receiving plenty attention in the last decades, because the need to understand, to analyze, to predict and to control real systems has been quickly growing with the technological and industrial progress. The objective of this thesis is to present a contribution for the development and implementation of Nonlinear Predictive Controllers based on Hammerstein model, as well as to its make properties evaluation. In this case, in the Nonlinear Predictive Controller development the time-step linearization method is used and a compensation term is introduced in order to improve the controller performance. The main motivation of this thesis is the study and stability guarantee for the Nonlinear Predictive Controller based on Hammerstein model. In this case, was used the concepts of sections and Popov Theorem. Simulation results with literature models shows that the proposed approaches are able to control with good performance and to guarantee the systems stability / O Controle Preditivo tem recebido muita aten??o nas ?ltimas d?cadas, visto que a necessidade de compreender, analisar, predizer e controlar sistemas reais tem crescido rapidamente com o avan?o tecnol?gico e industrial. O objetivo desta tese ? apresentar uma contribui??o para o desenvolvimento e implementa??o de Controladores Preditivos N?o lineares baseado no modelo de Hammerstein, bem como fazer uma avalia??o de suas propriedades. Neste caso, no desenvolvimento do Controlador Preditivo N?o Linear utiliza-se o m?todo de lineariza??o por degrau de tempo e ? introduzido um termo de compensa??o a fim de melhorar o desempenho do mesmo. A principal motiva??o desta tese ? o estudo e a prova da estabilidade para o Controlador Preditivo N?o Linear baseado no modelo de Hammerstein. Para isso utilizou-se os conceitos de setores e Crit?rio de Popov. Testes de simula??o com modelos da literatura mostram que as abordagens propostas s?o capazes de controlar com um bom desempenho e garantir a estabilidade dos sistemas
