UNITED SIMULATION MODELING OF GUIDANCE AND ATTITUDE CONTROL OF LARGE SCALE FLYING VEHICLE

In accordance with the characteristics of maneuverable-lunched large scale flying vehicle with solid rocket engine,this paper puts forward the general method of establishing a non-linear,time-varied,united simulation model of guidance and attitude control under great attitude condition with complete quantity and total disturbance.With the background of a certain type of large scale flying vehicle,the united simulation mathematical model of the flying vehicle is obtained by thoroughly considering the control system dynamic characteristics,flying vehicle centroid movement,attitude movement,mass-varied feature,elastic vibration,wind disturbance,etc.And then a visual,figurative,easy-understood,easy-extended,object-oriented,united simulation model of the flying vehicle is established in object-oriented simulation environment.The simulation results show that the united simulation model is accurate and effective.
