Time-delays are important components of many dynamical systems that describe coupling or interconnection between dynamics, propagation or transport phenomena, and heredity and competition in population dynamics. The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stabi...

In this paper a design of an observer for Lipschitz nonlinear systems in the presence of time-varying delay in outputs measurements is proposed. The structure of the proposed observer is based on the presence of a proportional integral term which permits the compensation of delay in the measurements outputs. The observer gain is a function of the maximum bound of the delay, the parameters of th...

this paper presents a theoretical approach to implementation of the “multi-realization of nonlinear mimo systems”. this method aims to find state-variable realization for a set of systems, sharing as many parameters as possible. in this paper a special nonlinear multi-realization problem, namely the multi-realization of feedback linearizable nonlinear systems is considered and an algorithm for ...

It is known that the presence of delays hinders performance achievable by a feedback control system, and it can even lead to closed-loop instability if not considered during design. For this reason, predictors are often included in loop, although they typically require knowledge exact value delay, which some applications hard obtain practice. This paper presents method design an observer simult...

Design of a state observer is an important issue in control systems and signal processing. It is well known that it is difficult to obtain the desired properties of state feedback control if some or all of the system states cannot be directly measured. Moreover, the existence of a lumped perturbation and/or a time delay usually reduces the system performance or even produces an instability in t...

This paper deals with the problem of reliable guaranteed cost control for linear time-delay systems via state feedback against actuator faults. Based on indirect adaptive method, the proposed delay-dependent memory controller with variable gains is established, whose gains are affinely dependent on the online estimations of fault parameters. In the frameworks of linear matrix inequalities, suff...
