In order to provide a basic and effective practical engineering tool for handling quality planning , analysing and evaluating , which is needed hi helicopter prototype development , this research work is launched on the fundation of comprehending the new aeronautical standard of united states army - ads - 33 , and has obtained the achievements as following : ( 1 ) performance definition of pcs according to the criteria requirements for an explicit helicopter , beginning at analysis of its missions . ( 2 ) establishment of a helicopter attitude controller , which can meet the criteria requirements , by using the technology of adaptive neural network model - inverse control ; implementation of two response types ( rts ) and two control modes ; evaluation of quantitative parameters according to the ads - 33 . ( 3 ) establishment of a helicopter trajectory contoller based on the attitude controller ; simulations of mission task elements ( mtes ) and evaluation of handling quality 為了給型號(hào)研制中飛行品質(zhì)的規(guī)劃、分析和評(píng)價(jià)提供基本的、有效的工程實(shí)用工具,本課題在充分消化理解美軍新航標(biāo)ads - 33的基礎(chǔ)上,作了以下工作: ( 1 )針對(duì)具體直升機(jī),從任務(wù)分析入手,根據(jù)規(guī)范要求確定對(duì)飛控系統(tǒng)的要求; ( 2 )應(yīng)用自適應(yīng)神經(jīng)網(wǎng)絡(luò)模型逆控制技術(shù),構(gòu)造了能夠滿足飛行品質(zhì)要求的直升機(jī)姿態(tài)控制器,實(shí)現(xiàn)了兩種響應(yīng)型式、兩種控制模式,并根據(jù)ads - 33進(jìn)行了定量指標(biāo)評(píng)估; ( 3 )在姿態(tài)控制器的基礎(chǔ)上,構(gòu)造了軌跡跟蹤器,進(jìn)行了任務(wù)科目基元仿真和飛行品質(zhì)評(píng)估。
Tflow ueses task element replaces with activity element defined by wfmc , and classifies task . to make wfms support transaction process well , in tflow , we give the conception of transactional task group restriction and post - transaction . combined use transactional task , transactional task group restriction and post - transaction can loosen the atomicity and isolation of traditional transaction , can also be as a practical method of dividing the long - running transaction 基于對(duì)工作流任務(wù)賦予不同的事務(wù)屬性,提出了“事務(wù)性任務(wù)組約束”以及“后繼事務(wù)”的概念,從而放松了事務(wù)的原子性、隔離性,提高了系統(tǒng)的開發(fā)性,并為長事務(wù)的劃分提供一種有效的、較實(shí)際的方法,節(jié)省了運(yùn)行成本,尤其是降低了進(jìn)行事務(wù)處理時(shí)的成本。
