| 摘 要： | 提出了一种新的模糊全阻尼算法.根据控制理论的思想,该算法在系统3个回路中分别加入不同的阻尼反馈网络,通过引入磁航向信息和充分利用系统本身速度信息来阻尼有害信息.由于水平回路阻尼网络的使用有一定的限制条件,系统设计了模糊控制器来控制阻尼网络的使用.仿真和试验证明:模糊全阻尼算法明显抑制了舒拉周期振荡和傅科周期振荡,有效地提高了捷联航姿系统的精度.

| Abstract: | A novel complete damped algorithm with a fuzzy controller is presented in this paper. According to the control theory, the system adds different damp feedback in three loops, which uses magnetic heading degree and velocities to damp errors. Because there are limits in using level damp networks, a fuzzy controller is used to decide whether the network is used. Simulation and experimental results show that the complete damped algorithm with a fuzzy controller can damp most Schuler and Foucault oscillations, and efficiently improves precision of strapdown AHRS. |
