Research On Several Flight Control Technologies

This dissertation studied further on engineering design of flight control laws for carrier vehicles in such aspects:multivariable robust decoupling control law design for carrier helicopters using H_∞optimizing method,when lands on carrier , aircraft works in backside region , and the flight velocity stability and flight path stability of landing are awaited analyzing,how to design the integrative control law for a variable geometry aircraft,the principium , configuration , and guidance law design of Instrument Carrier Landing System , as well as real-time simulation of the system.Firstly, H_∞loop-shaping multivariable robust decoupling optimizing method is studied in this paper, and a Attitude Control Attitude Hold flight control system for a carrier helicopter has been designed. And simulation verifies validity of the design. Then an elaborate analyse in manipulate ability, velocity stability and flight path stability of carrier aircrafts in backside situation is presented. And Automatic Power Compensating System with constant attack angle is illustrated to have considered all the three factors. Thirdly, a novel lateral flight control system, which uses differential stabilizer, differential spoiler and rudder to manipulate the aircraft, for variable geometry aircraft is designed. And later simulation also show the system is excellent. Last but not of the least importance, Instrument Carrier Landing System is researched and important kinematics is studied and explained, then corresponding simulation is performed.This dissertation contributes to the academic research and engineering application of guidance and control techiniques for development of guidance law and flight control law of carrier landings.
