工程系统定性理论及其在飞行控制中的应用
Qualitative theory for engineering system and its application to flight control
摘要
Abstract
In engineering systems,challenges such as constrained system inputs,model uncertainties,environmen-tal disturbance inputs,system mutations,or system failures often arise,making traditional qualitative theories like state controllability and observability difficult to apply.This paper describes the issues of traditional system state con-trollability and reachability through the analysis of model uncertainties.By modeling scenarios such as input constraints in aircraft actuators,additional inputs from environmental disturbances like gusts,system mutations during heavy air-drop or aerospace vehicle separation,and system failures,the paper investigates the controllability and stability deter-mination for systems under these different conditions.On this basis,the paper proposes definitions and determination methods for the engineering consistent controllability of system states and outputs within the same system,and also provides a definition for the engineering consistent observability of system states and outputs.These conclusions are able to unify traditional judgments on system controllability,reachability,and stability,and are analogous to the rapid-ity and accuracy determinations in classic control.For the development of high-performance aircraft,the paper outlines the analysis and verification requirements for design,wind tunnel,and flight tests.An explanation of engineering con-sistent controllability is provided through the design results of an actual longitudinal flight.关键词
