This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...

the objective of present research was to design, evaluate and compare drug release from two different dosage forms in pulsatile drug delivery system (dds) for metoprolol tartarate (mt) as tablet and capsule. pulsatile systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery ...

The objective of this study is to obtain the stabilizability conditions and a stabilizing composite state feedback control for exponential stabilization three-time-scale singularly perturbed linear time-invariant systems with multiple commensurate delays in slow variables two small parameters perturbation (TSPLTISD). do not depend on are valid all their sufficiently values. approach used work n...

evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...

Our interest lies in load balancing jobs large scale systems consisting of multiple dispatchers and FCFS servers. In the absence any information on job sizes, a popular method is SQ( $d$ ) policy, which uses queue length reported by s...

Considering the use of dynamical systems in practical applications, often only limited regions time or frequency domain are interest. Therefor, it usually pays off to compute local approximations used and domain. In this paper, we consider a structure-preserving extension frequency- time-limited balanced truncation methods second-order systems. We give full overview about first-order extend tho...
