由于增加了随动回路控制,三框架四轴平台系统要完成高精度射向装定必须综合考虑基座倾斜等情况。首先对目前工程上应用的按照框架角进行射向装定的方法应用于三框架四轴惯性平台系统时存在的问题进行了分析,提出了一种基于姿态解算的三框架四轴平台系统精确全方位射向装定新方法,并开展了工程验证与精度对比试验。试验结果表明该方法能够明显提高各种载体条件下射向装定的精度及稳定性,验证了该方法的正确性和工程适用性。
Due to the increased follow-up loop control, three-frame four-axis platform system to complete the high-precision shooting to the fixed installation must take into account the base tilt and so on. First of all, the problems existing in the application of three-axis four-axis inertial platform system when the method of shooting at the frame angle is applied to the current engineering are analyzed. A three-frame four-axis platform system based on attitude solution is proposed to be precise A full range of new ways to shoot fixed, and carried out engineering verification and accuracy comparison test. The experimental results show that this method can significantly improve the accuracy and stability of the heading assembly under various carrier conditions, and verify the correctness and engineering applicability of the method.
