摘　　要：姿态控制系统是功能多、构成复杂、可靠性要求高的关键分系统之一。传统的三自由度模型有较大局限性,不能全面反映飞行的实际情况。该文首先建立了姿态控制系统六自由度全量数学模型,包括控制方程和箭体运动两大部分。在此基础上,利用Matlab/Simulink仿真环境对姿态控制系统六自由仿真进行了研究。并通过对姿态运动简化分析和系统稳定性研究,设计了相应的数字校正网络和变增益系数,从而建立了姿态控制系统的全数值仿真模型。仿真实验表明,系统稳定,并且仿真结果具有较好的精度。Attitude control system is one of the key systems which have multi-plefunctions, complex structure, high reliability. The system programming and the choice of parameters must to be calculated, analysed and tested. So, the simulation test of the system has become necessary. The 3 DOF simulation has limitation and it can＇t reflect the practical situation. In this paper, the attitude control system math model of 6 DOF is established, including the control equation and rocket move. Then, the digital network and the gain coefficients are designed through analysing the stability of the system. The attitude control system simulation mode is constructed based on Matlab/Simulink. The test results show that the system is stable and its simulation data are better.
