This paper deals with two topics from state and parameter estimation. The first contribution of
this work provides an overview of techniques used for determining which parameters of a …

The analysis and control of time-delay systems has gained increasing interest in the last
decades due to the effectiveness of delay differential equations (DDEs) in modeling a wide …

This year is the 50th anniversary of Otto J. Smith's 1959 publication of a control design idea
commonly referred as the Smith predictor for the compensation of actuator delays. Actuator …

The theory of linear functional observers, which is the subject of this book, is increasingly
becoming a popular researched topic because of the many advantages it presents in state …

Consider the time periods required for a driver to react in response to large disturbances in
road traffic; for a signal sent from Houston to reach a satellite in orbit; for a coolant to be …

Time delays abound in dynamical systems. And long values of such delays often induce
instability. The idea of using “predictors” of the future state or output, initiated with the “Smith …

In this paper, we propose a high-gain observer design for nonlinear systems with time-
varying delayed output measurements. Based on a recent high-gain like observer design …

This paper presents a state observer for drift observable nonlinear systems when output
measurements are affected by a known and bounded time varying delay. The structure of …

This work presents a set of cascade high gain predictors to reconstruct the vector state of
triangular nonlinear systems with delayed output. By using a Lyapunov-Krasvoskii …

This technical note addresses the observer design problem for a class of continuous-time
dynamical systems with non-uniformly sampled measurements. More specifically, we …
