Status Update Control and Analysis Under Two-Way Delay

نویسندگان

چکیده

We study status updating under two-way delay in a system consisting of sampler, sink, and controller residing at the sink. The drives sampling process by sending request packets to sampler. Upon receiving request, sampler generates sample transmits update packet Transmissions both encounter random delays. develop optimal control policies minimize average age information (AoI) using tools Markov decision processes two scenarios. begin with having most one active i.e., generated for which sink has not yet received packet. Then, as main distinctive feature this paper, we initiate pipelined-type studying requests. Furthermore, conduct AoI analysis deriving expressions $\ZW{1}$ , notation="LaTeX">$\ZW{2}$ notation="LaTeX">$\Wone$ policies. According policy, whenever is delivered new inserted into system. policy operates similarly, except that can hold sent after waiting time function current AoI. Numerical results illustrate performance each varying parameter values.

Multiple Model Control for Teleoperation Under Time Delay MULTIPLE MODEL CONTROL FOR TELEOPERATION UNDER TIME DELAY

Performance and stability of bilateral teleoperation control systems are adversely affected by variations in environment dynamics and time delay in communication channel. Prior relevant research in the literature has mainly yielded control algorithms that sacrifice performance in order to guarantee robust stability. In contrast, this thesis proposes methods to deal with these two main problems ...

Comparing two testing procedures in unbalanced two-way ANOVA models under heteroscedasticity‎: Approximate degree of freedom and parametric bootstrap approach

‎The classic F-test is usually used for testing the effects of factors in homoscedastic two-way ANOVA models‎. ‎However‎, ‎the assumption of equal cell variances is usually violated in practice‎. ‎In recent years‎, ‎several test procedures have been proposed for testing the effects of factors‎. ‎In this paper‎, ‎the two methods that are approximate degree of freedom (ADF) and parametric bootstr...

Status Update on the Isac Control System

Implementation and commissioning of the EPICS based control system for the ISAC radioactive beam facility was completed. The target ion source, mass separator, and low-energy beam-lines started beam production for experiments. In parallel, controls for the accelerator system, a radio-frequency quadrupole followed by a drift-tube linac, and several high-energy beam-lines were implemented and com...
