Robustness of feedback stabilization is studied for causal linear time-invariant input-output systems defined on the full time axis Z. The signal space setting used includes also certain unbounded signals. This study has been possible due to the use

Robust non-fragile feedback stabilization is studied for causal linear time-invariant (LTI) input–output systems defined in an L 2( ) signal space setup, or equivalently in an L 2(j ) setup in the frequency domain. Two-operator descriptions for the

L"2 and L"1 optimal linear time-invariant (LTI) approximation of discrete-time nonlinear systems, such as nonlinear finite impulse response (NFIR) systems, is studied via a signal distribution theory motivated approach. The use of a signal distributi

This note provides a tutorial treatment of the basic (unilateral) Laplace transform method for solving initial value problems for linear constant coefficient differential equations with terms that contain derivatives of the input. The input is allowe

Some methods for constructing rational approximants to distributed delays, such as those occurring in the the theory of the Smith predictor, are analysed, and approximation error bounds are derived. The von Neumann inequality is introduced as a metho

Linear time-invariant (LTI) modelling of nonlinear finite impulse response (NFIR) systems is studied from a control point of view. Nearly linear NFIR systems and their control-relevant properties are analysed in detail. The main modelling interest is

Least-squares linear time-invariant (LTI) approximation of discrete-time nonlinear systems is studied in a generalized harmonic analysis setting extending an earlier result based on quasistationary signals. The least-squares optimal LTI model is such

Optimal squared error and absolute error-based approximation problems for static polynomial models of nonlinear, discrete-time, systems are studied in detail. These problems have many similarities with other linear-in-the-parameters approximation pro

An optimal squared error based approximation problem for static polynomial models is solved. This problem is similar to an optiInal approximation problem for linear time-invariant (LTI) models. Corresponding absolute error based approximation problem

Best linear time-invariant (LTI) approximations are analysed for several interesting classes of discrete nonlinear time-invariant systems. These include nonlinear finite impulse response systems and a class of nonsmooth systems called bi-gain systems
