摘　　要：舰船惯性导航系统根据运动状态在水平阻尼和无阻尼两种工作状态间转换,载体运动加速度引起的系统误差和状态转换时产生的超调误差会导致惯导的动态性能变差。针对传统阻尼方法的局限性,采用自适应控制方法设计了平台式惯导的水平阻尼网络,根据运动加速度的大小,适时改变阻尼网络参数,使舰船机动造成的系统误差最小,并相应提出了抑制状态转换超调误差的方法。理论分析与仿真结果表明,该方法能有效改善惯导的动态性能。The inertial navigation system （INS） of ships switches between two modes of undamped navigation and horizontal-damped navigation according to the state of motion,during which the system error caused by the acceleration of the ship and the overshoot error resulted from the frequent switches between two modes may degrade the dynamic performance of the INS .Considering the limitations of traditional damping method,the adaptive control method was applied to design a level damping network of platform inertial navigation .The damping network parameters were changed adaptively according to the acceleration,thus to make the system error minimum.And a method for restraining the overshoot error caused by mode switching was also proposed .Theoretical analysis and simulation result shows that the method can improve the dynamic performance of the INS effectively .
