# velocity constant

## velocity constant

[və′läs·əd·ē ‚kän·stənt]
(control systems)
The ratio of the rate of change of the input command signal to the steady-state error, in a control system where these two quantities are proportional.

In flocking problem for a group of AUVs, one important task is to achieve convergence of the heading angle of each AUV in the group so that they will follow the same path keeping forward velocity constant.
Interestingly, this relationship conveniently produced a series of incident waves with different curved segments by adjusting the hammer diameter while keeping the hammer length, curvature radius, and impact velocity constant.
In addition, the reaction kinetics were studied too and the velocity constant was calculated.
Population size 100 Number of iterations 100 Velocity constant,c1 1.5 Velocity constant,c2 1.5 Inertia weight factor, W 0.5 Table 1: PID tuning values.
When a black hole increases in mass, it must also increase in angular momentum in order to keep the angular velocity constant up to the maximum speed of rotation set by the periphery being unable to exceed the speed of light, which thus limits the ultimate size a black hole can grow to.
[v.sub.o] and [v.sub.s] are the reaction initial and steady-state velocities, respectively, and [k.sub.app] denotes the apparent first-order velocity constant for interconversion between [v.sub.o] and [v.sub.s].
Assumptions: each grain develops with random velocity constant in time during the reaction; different grains may have different velocity.
In the first one (type I), phase inversion is achieved by varying the input superficial velocities of both oil and water phases, while keeping the total mixture velocity constant at each run (e.g.
By using the Vectra MFL tool with its active speed control and gas by-pass system, BJ will keep the tool velocity constant throughout the run, thereby assuring that all data captured is accurate and of the highest resolution.
As the reel fills, its speed changes to compensate for its fattening diameter, keeping tangential velocity constant. The reel also moves toward and away from the flyer to distribute the wraps of the cable on the reel.
