摘要
在分析三轴仿真转台模拟方位可连续旋转的垂直发射飞行器姿态运动缺陷的基础上,提出一种能够模拟飞行器俯仰、滚动姿态不小于±180°变化范围并且航向姿态变化无限大的四轴仿真转台方案,进行四轴转台结构布局分析和控制建模,并设计基于"切换运动机制"的四轴协调运行控制规律,完成转台控制过程中的平滑切换措施设计及仿真验证。证明了四轴仿真转台及其协调运行控制方案,为方位连续旋转的垂直发射飞行器全程飞行姿态运动的模拟提供了一种连续、实时、高效的仿真方法。
There are defects in the pose movement simulation of vertical launching aerocraft which can circumrotate continuously in yaw with three-axis flight motion simulator. Based on analysis of these defects,a four-axis project which could be applied to the situation of the changing range of vehicle pitch pose and vehicle roll attitude more than ±180° and the changing range of vehicle course pose towards infinite greatness was proposed. The structure of the four-axis flight motion simulator was analyzed and the control model was made. Above all, a four-axis concerted control law was designed with ＂ switching movement mechanism＂, and a smooth switch measure in the control process of flight motion simulator was designed too, then the result was validated with simulation. A continuous, real-time and high-efficient simulation method for the pose movement of vertical launching aerocraft which could circumrotate continuously in yaw was confirmed.
