In this paper, we propose a new time-domain design of an Unknown Input functional Observer (UIFO) for delayed singular systems with known and unknown inputs. The order of this observer is equal to the dimension of the vector to be estimated. Constant and variable delays act on the known input vectors and a variable state delay is also taken into account. The proposed approach is based on the un...

The design of state feedback controllers and observers are proposed in this paper for a class of multi-input-multi-output linear systems with uncertainties and time varying delays both in states and control inputs. By using Lyapunov stability theorem, a sufficient condition is found for computing the state feedback gains of controllers and the gains of observers in order to regulate the closed-...

In Communication‐Based Train Control (CBTC) systems, random transmission delays and packet drops are inevitable in the wireless networks, which could result in unnecessary traction, brakes or even emergency brakes of trains, losses of line capacity and passenger dissatisfaction. This paper applies predictive function control technology with a mixed  H H / 2 contr...

This decade there has been renewed interest in research on time-delay systems (TDS) due to the major influence of delays, particularly in communication networks, on control systems. Thus many applied and theoretical research works have been carried out recently on time-delay systems [1], [2], [3], [4], [5], [6]. The book intends to ”present a systematic and comprehensive treatment of robust H∞ ...

This letter studies the consensus tracking control for multi-agent systems (MASs) of general linear dynamics considering heterogeneous constant known input and communication delays under a directed graph containing spanning tree. First, open-loop stable MASs, distributed predictive observer is proposed to estimate error construct that does not involve any integral term (which time-efficient in ...

This paper proposes a sliding-mode control scheme for a class of nonlinear systems with multiple time delays, in the state variables and in the output signal. The unmeasured state of the system is estimated by an asymptotic observer for the zero dynamics and high-gain observers connected in cascade for a chain of integrators with a nonlinear input disturbance which compose the complete state. T...
