Slow-varying
WebbSlowly varying system ẋ = A (t)x. Abstract: A limiting case of great importance in engineering is that of slowly varying parameters. For systems described by \dot {x} = A (t)x , one would intuitively expect that if, for each t , the frozen system is stable, then the time-varying system should also be stable. Provided A (t) is small enough ... http://www.cdam.lse.ac.uk/Reports/Files/cdam-2007-03.pdf

WebbThis first requires that the system be slowly time-varying. A second approach that has come into prominence only recently is the control of linear parameter-varying systems. We should note that most of the techniques that are used to design controllers for linear time-varying systems are modifications of their time-invariant counterparts. For this WebbVarying requirements and the complications of international politics meant that progress on the initiative was slow. 不同的要求和国际政治的复杂性意味着该倡议的进展缓慢。 Still in use today , the M198 is, in turn , being slowly replaced by the M777 Ultralightweight howitzer , which weighs nearly half as much and can be more easily moved .
WebbWhen the exciting frequency is relatively small, by regarding the whole exciting term as a slow-varying parameter, the original system can be transformed into a generalized autonomous system. The phase space can be divided into three regions by the nonsmooth boundaries, in which the trajectory is governed by three different subsystems, respectively.

An example of an unbounded f of this kind can be obtained by adding the additive version of any unbounded slowly varying function; e.g., f(x) = (-1)[x] + logx. floyd mayweather top 5 fighters
