提出了用于多变量耦合系统稳定性分析的非解耦方法，该方法不需要增加解耦措施，只需通过方程之间的变换，就可以判别出耦合系统的稳定性．将此法应用到大姿态复合运动三轴耦合平台系统的稳定性分析中，比较分析结果与仿真结果后，证明方法是有效的．通过分析和仿真得到的平台系统稳定临界姿态角为平台尝试大姿态角运动提供了理论依据．
A non-decoupling method for the stability analysis of multivariable coupling systems is proposed. This method does not require additional decoupling measures. The stability of the coupled system can be determined simply by changing the equations. This method is applied to the stability analysis of the system of three-axis coupled platform with large-scale compound motion. After comparing the results with the simulation results, the method is proved to be effective. The steady critical attitude angle of the platform system obtained by analysis and simulation provides a theoretical basis for the platform to attempt large attitude angular motion.
