| 摘 要： | 针对惯导系统传统阻尼方法存在的阻尼网络设计复杂、状态切换产生较大超调误差等主要问题,提出了一种基于变阻尼比例控制的惯导水平内阻尼方法,在无阻尼惯导东向、北向水平修正回路中增加一条前向比例环节通道,通过合理设计比例参数,利用提取的加速度信息进行惯导水平内阻尼,抑制惯导中舒拉振荡误差.相对于传统阻尼方法,该方法使得阻尼网络设计大为简化.该方法通过连续调整比例控制系数,可实现阻尼系数的连续线性修正,能有效抑制无阻尼状态向阻尼状态切换时超调误差.

| Abstract: | In order to simplify the design of traditional damping network in inertial navigation system(INS) and suppress its overshoot errors while switching from non-damping state to damping state,a continuously adjustable horizontal inner damping method using proportional control is proposed.A proportional control segment is added in the east and north correction loops of non-damping INS respectively.Accelerations are used to damp the Schuler periodic errors of INS with the proportional control segment.The design o... |
