Time-scale transformations of discrete time processes∗

This paper investigates the effects of temporal aggregation when the aggregation frequency is variable and possibly stochastic. The results that we report include, as a particular case, the well-known results on fixed-interval aggregation, such as when monthly data is aggregated into quarters. A variable aggregation frequency implies that the aggregated process will exhibit time-varying paramet...

Discrete Time Scale Invariant Markov Processes

In this paper we consider a discrete scale invariant Markov process {X(t), t ∈ R} with scale l > 1. We consider to have some fix number of observations in every scale, say T , and to get our samples at discrete points α, k ∈ W, where α is obtained by the equality l = α and W = {0, 1, . . .}. So we provide a discrete time scale invariant Markov (DT-SIM) process X(·) with parameter space {α, k ∈ ...

Optimal Finite-time Control of Positive Linear Discrete-time Systems

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...

Discrete Time Markov Processes

What follows is a quick survey of the main ingredients in the theory of discrete-time Markov processes. It is a birds' view, rather than the deenitive \state of the art." To maximize accessibility, the nomenclature of mathematical probability is avoided, although rigor is not sacriiced. To compensate, examples (and counterexamples) abound and the bibliography is annotated. Relevance to control ...
