The phrase "varying delay" is grammatically correct and can be used in written English.
It is commonly used to describe a situation where the amount of time between events or actions changes. Example: The train schedules have been affected by varying delays due to heavy rain and flooding on the tracks.
Figure 11 Performance comparison between the modeling method and proposed method with varying delay thresholds.
Employing the Lyapunov-Ktasovskii approach, literature [19 21] requires both the upper bound of the time-varying delay and additional information on the derivative of the time-varying delay, while literature [17, 18, 22, 23] has no restriction on the derivative of the time varying delay, which allows a fast time-varying delay.
d ( t ) is time varying delay and satisfies 0 < d ( t ) ≤ h and d ˙ ( t ) ≤ μ.
Figure 12 Network lifetime varying delay requirement for comparing ORD and ORIA.
Figure 13 Ratio of late packets varying delay requirement for comparing ORD and ORIA.
Jitter is defined as the varying delay of packets that arrive at the receiver.
Besides the nonlinear couplings, the network model in this paper can possess parametric disturbances, internal time-varying delay, discrete time-varying delay and distributed time-varying delay.
The systems under consideration involve state time-varying delay.
The first controller fully involves the information of time-varying delay and the second one is delay-independent under the case that time-varying delay is unknown.
By introducing a stochastic variable which satisfies Bernoulli distribution, the information of probabilistic time-varying delay is equivalently transformed into the deterministic time-varying delay with stochastic parameters.
However, such disadvantage as time-varying delay in AMD control systems impedes their application in practices.
