In this paper, an approach is proposed to the fault detection in multirate sampled-data (MSD) systems with multiple time-delays in both input and output channels. The background of our study is the increasing demands for fault detection in complex, distributed process control systems, where the plant, controllers, sensors and actuators are networked by standardized bus systems. The core of the ...

In this paper, the authors considered a class of fractional-order Hindmarsh-Rose (HR) neuron model with time-delays and widely investigated the dynamical behaviors of considered fractional-order HR model with time-delays. Some new sufficient conditions are derived by using the proposed stability theory of linear fractional-order systems to guarantee the stability results of fractional-order HR ...

In this preliminary paper we study the stability property of a consensus on the average algorithm in arbitrary directed graphs with respect to communication/sensing timedelays. The proposed algorithm adds a storage variable to the agents’ states so that the information about the average of the states is preserved despite the algorithm iterations are performed in an arbitrary strongly connected ...

A new approach for observer-based feedback control of time-delay systems is developed. Timedelays in systems lead to characteristic equations of infinite dimension, making the systems difficult to control with classical control methods. In this paper, a recently developed approach, based on the Lambert W function, is used to address this difficulty by designing an observer-based state feedback ...

ABSTRACT Over the past few years there has been an increasing interest in using computer simulation models to create Interactive Learning Environments ILEs, for management education. Particularly when combined with System Dynamics simulation models, ILEs have proved their validity in a variety of different fields. Starting from these considerations, this paper focuses on the use of System Dynam...

A Prediction-error-method tailored for model based predictive control is presented. The prediction-error method studied are based on predictions using the Kalman filter and Kalman predictors for a linear discrete-time stochastic state space model. The linear discrete-time stochastic state space model is realized from a continuous-discrete-time linear stochastic system specified using transfer f...

We consider delay differential algebraic equations (DDAEs) to model interconnected systems with time-delays. The DDAE framework does not require any elimination techniques and can directly deal with any interconnection of systems and controllers with timedelays. In this framework, we analyze the properties of the H-infinity norm of interconnected systems with time-delays. We show that the stand...

This paper focuses on the effects of constant timedelays on force-reflecting teleoperation systems. The wave variable method is used to investigate its effectiveness in the presence of time delays. The master (joystick) and the slave system (remote mobile robot) dynamics and the controller are modeled in the Matlab environment. Performance of the teleoperation system controlled by the wave vari...

The material presented in this chapter is based on important advances realized in “attophysics” which make feasible to follow the motion of electrons in atoms and molecules with attosecond-level time resolution. In this context, timedelays have been recently determined in the process of photoionization by extremeultra-violet (xuv) pulses and the question of the significance of these measured de...
