摘　　要：针对导弹陀螺仪结构复杂、建立物理模型困难的问题,文中将混沌理论引入陀螺仪漂移预测。依据吸引子理论分析漂移数据,在得到漂移过程为近似混沌过程的基础上,用Wolf模型对未来漂移趋势进行预测,并通过灰色误差检验方法对预测方法和结果进行了评价。在保证预测精度的前提下,该方法具有无需知道陀螺物理模型的特点。通过对某型号导弹陀螺漂移仿真实验,证明了这种方法的有效性和实用性。Aiming at the problem that the construction of missile gyroscopic is very complex, and it＇s diffieult to get the physical model, the paper brought in chaos theory to the field of gyroscopic drift forecasting. Firstly, the paper analyzed the drift data according to chaotic attractor. Then on the basis of confirming that missile gyroscopic drift was a chaotic process, the paper made prediction of gyroscopic drift using algorithm based on largest Lyapunov exponent. The method provided has the merit of being needless of physical model. Simulated experiment had showed that the method was valid and acceptable.
