Identification of uncertain MIMO Wiener and Hammerstein models
(Pergamon-Elsevier Science Ltd, 2011-12-14)
Several approaches can be found in the literature to perform the identification of block oriented models (BOMs). In this sense, an important improvement is to achieve robust identification to cope with the presence of ...
Síntese das técnicas de identificação de sistemas não lineares: estruturas de modelo de Hammerstein-Wiener e NARMAX
(Universidade do Vale do Rio dos Sinos, 2016-09-14)
The task of system identification is far from being a new one. It was initially proposed in the mid of the 20th century, and had then been extensively developed for linear systems, due to the demands of that time concerning ...

Controle preditivo não linear baseado no modelo de Hammerstein com prova de estabilidade
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2009-03-27)
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 ...
Wiener and Hammerstein uncertain models identification
(Elsevier Science, 2009-07)
Block-oriented models have proved to be useful as simple nonlinear models for a vast number of applications. They are described as a cascade of linear dynamic and nonlinear static blocks. They have emerged as an appealing ...
Estudio experimental de las versiones clásicas de evolución diferencial para la estimación de parámetros de un modelo de Wiener-Hammerstein
(2022)
The Wiener-Hammerstein models are a class of non-linear models set by a cascade connection of two linear dynamic blocks separated by a block that represents a static-type non-linearity. This article approaches the ...
Identificação de modelos de Hammerstein e Wiener para sistemas não lineares multivariáveis utilizando métodos de subespaços
(Universidade Federal de Minas GeraisUFMG, 2016-08-01)
The subspace methods for system identification are a powerful tool for modelingvmultivariable linear systems in state space. These methods do not require that all statesvare directly measured. Combining the methods of ...
Estimação e compensação de não linearidades inerentes aos atuadores dos processos industriais
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2009-12-16)
The oscillations presents in control loops can cause damages in petrochemical industry. Canceling, or even preventing such oscillations, would save up to large amount of dollars. Studies
have identified that one of the ...
Robust model predictive control of Hammerstein systems
(Nova Science Publishers, 2015)
There are very few controller design techniques that can be proven to stabilize processes in the presence of nonlinearities and constraints. Model predictive control (MPC) is one of these techniques. For this reason, there ...
An efficient CS-CPWL Based Predistorter
(Spolecnost Pro Radioelektronicke Inzenyrstvi, 2009-06)
We study the performance of Hammerstein predistorters (PD) to model and compensate nonlinear effects produced by a high power amplifier with memory. A novel Hammerstein model is introduced that includes, as the basic static ...
