题目飞机起落架收放系统分布式控制设计飞机起落架收放系统分布式控制设计摘要飞机起飞和降落过程中，起落架控制系统会对其安全性产生直接影响。集中式控制系统有着较低的可靠性和较高的布线复杂度，同时在应用方面时效性不强，无法与控制系统发展过程中的实际应用需求相契合，背景下正式诞生分布式控制系统。此次在TTCAN通信协议基础上进行飞机起落架分布式控制系统的针对性设计，对TTCAN网络进行了具体性能的分析探讨。针对性的设计了起落架收放系统的电气控制部分，在系统设计过程中对总线型和星型混合拓跋结构进行了应用，整体着较为简单的系统布线，同时有着较好的扩展性，系统的故障处理能力和故障检测能力得到了显著提高。同时去除了系统控制单元、传感器、总线以及执行器存在的冗余设计，全面提高了系统的可靠性。在TTCAN通信协议基础上设计的起落架分布式控制系统，使得布线重量和布线复杂性得到了显著降低，全面提高了系统的实时性和可靠性，与系统使用需求相契合，可以进一步提高飞机起落架收放控制系统的经济性、安全性等，具有一定的现实意义。关键词：飞机起落架；分布式；TTCAN总线；拓扑结构IAircraftLandingGearDistributedControlSystemandReliabilityAnalysisAbstractDuringtake-offandlandingofanaircraft,thelandinggearcontrolsystemwilldirectlyaffectitssafety.Thecentralizedcontrolsystemhaslowreliabilityandhighwiringcomplexity.Atthesametime,itisnottime-sensitiveinapplicationandcannotmeettheactualapplicationrequirementsinthedevelopmentprocessofthecontrolsystem.Underthebackground,thedistributedcontrolsystemwasformallyborn.BasedontheTTCANcommunicationprotocol,thetargeteddesignoftheaircraftlandinggeardistributedcontrolsystemwascarriedout,andthespecificperformanceoftheTTCANnetworkwasanalyzedanddiscussed.Theelectricalcontrolpartofthelandinggearretractablesystemisdesignedinatargetedmanner.Duringthesystemdesignprocess,thebus-typeandstar-typehybridTuobastructureisapplied.Theoverallsystemwiringisrelativelysimple,andatthesametime,ithasbetterscalability.Thesystem'sfaulthandlingcapabilitiesandfaultdetectioncapabilitieshavebeensignificantlyimproved.Atthesametime,theredundantdesignofthesystemcontrolunit,sensor,busandactuatorisremoved,andthereliabilityofthesystemiscomprehensivelyimproved.ThelandinggeardistributedcontrolsystemdesignedonthebasisoftheTTCANcommunicationprotocolsignificantlyreducesthewiringweightandwiringcomplexity,andcomprehensivelyimprovesthereal-timeperformanceandreliabilityofthesystem.Itmeetstheneedsofthesystemandcanfurtherimprovetheaircraft'slandinggear.Theeconomy,safety,etc.ofthecontrolsystemoftheretractableandretractablelandinggearhavecertainpracticalsignificance.Keywords：AircraftLandingGear;Distributed;TTCANBus;TopologicalIIstructureIII目录摘要.................................................................................................................................IAbstract................................................................................................................................II目录..............................................................................................................................III第一章绪论....................................................................................................................41.1研究背景........................................................................................................................41.2国内外研究现状............................................................................................................41.3研究意义..................
