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 为了给型号研制中飞行品质的规划、分析和评价提供基本的、有效的工程实用工具,本课题在充分消化理解美军新航标ads - 33的基础上,作了以下工作: ( 1 )针对具体直升机,从任务分析入手,根据规范要求确定对飞控系统的要求; ( 2 )应用自适应神经网络模型逆控制技术,构造了能够满足飞行品质要求的直升机姿态控制器,实现了两种响应型式、两种控制模式,并根据ads - 33进行了定量指标评估; ( 3 )在姿态控制器的基础上,构造了轨迹跟踪器,进行了任务科目基元仿真和飞行品质评估。
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 基于对工作流任务赋予不同的事务属性,提出了“事务性任务组约束”以及“后继事务”的概念,从而放松了事务的原子性、隔离性,提高了系统的开发性,并为长事务的划分提供一种有效的、较实际的方法,节省了运行成本,尤其是降低了进行事务处理时的成本。
