三框架四轴平台虽然满足了导弹武器系统全姿态机动的需求,但由于增加了一个框架角,弹体姿态的解算却比三轴平台复杂得多。根据随动回路的工作特点,推导出了三框架四轴惯性平台系统各种工况下由四个框架角输出解算弹体的三个姿态角的公式。
Although the three-frame four-axis platform meets the requirements of all-attitude maneuvering of missile weapon system, the solution of projectile attitude is much more complex than the three-axis platform due to the addition of a frame angle. According to the working characteristics of the servo loop, the formulas of the three attitude angles of the projectile are derived from the four frame angles under various operating conditions of three-frame four-axis inertial platform system.
