Linear approximations of nonlinear FIR systems for separable input processes  
Nonlinear systems can be approximated by linear time-invariant (LTI) models in many ways. Here, LTI models that are optimal approximations in the mean-square error sense are analyzed. A necessary and ......

Benefits of the Input Minimum Phase Property for Linearization of Nonlinear Systems  
Abstract Linear approximations,of nonlinear systems,can be obtained,by fitting a linear model to data from a nonlinear system, for example, using the prediction-error method. In many situations, the t......

Nonparametric initial estimates for Wiener-Hammerstein systems  
This paper studies the generation of nonparametric initial estimates for Wiener- Hammerstein systems. The kernel idea is to replace the original structure by an alternative representation that is easi......

LTI APPROXIMATIONS OF SLIGHTLY NONLINEAR SYSTEMS: SOME INTRIGUING EXAMPLES  
Approximations of slightly nonlinear systems with linear time-invariant (LTI) models are often used in applications. Here, LTI models that are optimal approximations in the mean-square error sense are......

Initial estimates for the dynamics of a Hammerstein system  
This paper studies the generation of initial estimates for the dynamic part of a Hammerstein model. Replacing the static nonlinear system by a static gain plus a nonlin- ear noise source shows that AR......

Upper bounding the variations of the best linear approximation of a nonlinear system in a power sweep measurement  
I n many engineering applications, linear models are preferred, even if it is known that the system is nonlinear. A large class of nonlinear systems, excited with random excitations, can be represente......

Robustness Issues of the Equivalent Linear Representation of a Nonlinear System  
In many engineering applications, linear models are preferred, even if it is known that the system is nonlinear. A large class of nonlinear systems, excited with a 'Gaussian' random excitation, can be......

On Multivariable and Nonlinear Identification of Industrial Robots  
Abstract The main objective of the thesis is the identification of flexibilities and nonlinearities in mathematical models of industrial robots. In particular, a nonparametric frequency-domain estimat......
