基于一种9加速度计配置方案,应用对数算法对无陀螺捷联惯导系统的角速度进行求解,对传统对数算法解算角速度进行了推导,详细分析了该方法解算角速度造成不能判断符号的原因,并针对此问题提出了积分法和一种准无陀螺方法来判断符号的解决方案.对传统对数算法和改进的对数算法解算角速度进行了仿真试验,验证了改进的对数算法可以判断解算角速度的符号.
Based on a 9-accelerometer configuration scheme, the angular velocity of the gyroless SINS was solved by a logarithmic algorithm. The angular velocity of the traditional logarithmic algorithm was deduced. The angular velocity of the system was analyzed in detail. , And put forward the integral method and a kind of quasi-gyro-free method to judge the symbolic solution to this problem.Experimental simulations on the traditional angular speed and the traditional logarithmic algorithm are carried out to verify the improved logarithm The algorithm can determine the sign of solving the angular velocity.
