Yet rapid and accurate calculation of preestimate time proves to be difficult. 快速精確地計(jì)算重合閘時(shí)間預(yù)估值是其難點(diǎn)。
It would be more difficult and more unpredictable to preestimate accurately the environmental condition in which the enterprise locates. 要對(duì)一個(gè)組織所處的環(huán)境條件做出比較準(zhǔn)確的預(yù)測,變得越來越困難,甚至呈現(xiàn)出越來越多的“長期不可預(yù)測”現(xiàn)象。
After state preestimate and state movement analysis, a discrete sliding mode controller which can essentially avoid the chattering phenomenon is designed. 通過系統(tǒng)狀態(tài)預(yù)估及對(duì)狀態(tài)運(yùn)動(dòng)的分析，設(shè)計(jì)了可以完全消除系統(tǒng)抖振的滑?？刂破鳌?/li>
This paper presents a stochastic calculus approach to this problem, deduces formulae to calculate the preestimate time, gives some thoughts of concrete realization. 本文提出了解決這一難題的隨機(jī)分析方法，導(dǎo)出了時(shí)間預(yù)估值的計(jì)算公式，并給出了具體實(shí)現(xiàn)思路。
Calculation of Preestimate Time for Adaptive Reclose Using Stochastic Calculus 基于隨機(jī)分析的自適應(yīng)重合閘時(shí)間預(yù)估值計(jì)算
