大型弹道式飞行器六自由度仿真研究与展望

本文针对大型弹道式飞行器传统建模和仿真方法的局限性，采用多种运动形态一体化建模方法，建立了飞行器全干扰，全量，全通道，时变非线性六自由度模型，并进行了数字仿真和接入部分实装的半实物仿真。

THE RESEARCH AND EXPECTATION OF SIX-DEGREE-OF-FREEDOM SIMULATION OF LARGE SCALE BALLISTIC VEHICLE

This paper aims at the limitation of traditional modeling methodology and analysis method of large scale ballistic vehicle,adopts incorporate modeling method of various movement forms and establishes complete disturbance,complete quantity,complete passage and time variant non linear six degree of freedom model of ballistic vehicle,and carry out mathematical and parcel hard in loop simulation.The application of the model in the field of control system design,system performance estimation,error analysis,accuracy evaluation,flight effect predication and launch technique decision have gained satisfactory effect which indicates the six degree of freedom model is much more correct and accordance with real circumstance of flight.It develops and deepens the research of system analysis and simulation.
