摘要
本文对自适应滤波方法在惯导系统中的应用进行了可行性研究。本文讨论了惯导系统的状态方程和测量方程,也讨论了在实际应用条件下简化状态方程的方法,给出了适用于惯导系统使用的带平滑的自适应滤波器,并用带平滑的自适应滤波器对系统的状态和误差源的统计特性进行估计。仿真结果表明,带平滑的自适应滤波器具有良好的跟踪性能。即使事先对误差源的统计特性了解很少,滤波器也能比较准确地估计出系统的状态。
The state equation and measurement equation of inertial navigation system are discussed and a symplified state equation is suggested for practical use. The statistical characteristics of the system state and the error source are estimated by using smooth adaptive filter. The simulation results have shown that the smooth adaptive filter is of a satisfactory traceablity even if the state characteristics are little known.
