【摘要】 以惯性导航平台漂移误差模型为例,研究了一类非线性系统仿真模型的建立及其线性化的过程。我们把引起平台漂移的各种误差因素综合考虑在内,建立了描述平台漂移的比较完整的动态模型。该模型既便于随着所选择误差参数的增减而进行扩充或简化,也便于根据平台型号的不同做相应的修正,从而保证较好的可移植性更多还原

【Abstract】 Based on an inertial navigation platform drift error model, the modeling and linearizing process of a class of nonlinear system is studied in this paper. By taking into consideration various error sources that cause the platform drift, a complete dynamic model is derived to describe the platform drift. It is convenient to adapt the model to the change of selected error parameters’ number and the variation of platform type, thus ensuring the model’s transferability.更多还原
