基于惯性传感器输出匹配的舰船变形估计方法
Deformation Estimation of Warship Based on the Match of Inertial Sensors' output *
摘要
Abstract
Deformation of large ship may occur while sailing in the ocean, because of wind, wave, change of payload,sunshine and so on, this deformation will greatly affect the accuracy of attitude which is needed by the shipboard weapons. To solve this problem, IMUs (Inertial Measurement Unit, laser gyros and accelerometers)are installed on various action stations of the large ship,the output message about velocity increment and angular velocity of the IMUs are utilized to mach with the output of the inertial navigation system of the ship, Kalman filtering also used to estimate deformation angle. Simulation results show that, under middle ocean condition, the method presented can estimate the deformation of the ship in the accuracy less than 1 minute of arc within 10 seconds.关键词
