The pointwise completeness and the pointwise degeneracy of linear discrete-time different fractional order systems [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
Necessary and sufficient conditions for the pointwise completeness and the pointwise degeneracy of linear discrete-time different fractional order systems are established. It is shown that if the fractional system is pointwise complete in one step (q = 1)

Development of Discrete-Time Waterjet Control Systems Used in Surface Vehicle Thrust Vectoring

open access: yesJournal of Marine Science and Engineering, 2022
To create an autonomous surface vehicle, the microcontroller that will be responsible for the vessel’ s response will have access to both engine thrust controls and steering controls. In the case of a vehicle with waterjet propulsion, the term “controls”

Discrete-Time Interest Rate Modelling [PDF]

open access: yes, 2009
This paper presents an axiomatic scheme for interest rate models in discrete time. We take a pricing kernel approach, which builds in the arbitrage-free property and provides a link to equilibrium economics.

Relationship between the observability of standard and fractional linear systems

open access: yesArchives of Control Sciences, 2017
The relationship between the observability of standard and fractional discrete-time and continuous-time linear systems are addressed. It is shown that the fractional discrete-time and continuous-time linear systems are observable if and only if the ...
