摘要
针对某小型自旋飞行器为适应惯性测量单元(IMU)量程,通过隔离装置将IMU与飞行器进行隔离的特殊要求,设计了一款适用于中低速自旋飞行器的轻、快、稳、准的小型隔离装置。根据设计要求、使用环境和飞行器IMU测量原理,对隔离装置进行了结构设计;建立了隔离装置机电系统的数学模型,对其动态性能进行理论分析和控制器校正设计,并通过专门设计的实验平台对隔离装置的解旋性能进行试验研究,整定了控制参数,得到以下结论:隔离装置的转速误差率均低于设计要求的1%,解旋效果较好,控制精度较高,速度发生突变时系统响应速度较快。论述对深入研究自旋飞行器隔离装置解旋结构提供了新的思路,具有较高的工程应用价值。
In order to make the small spinning aircraft adapt to the range of the inertial measurement unit(IMU),a light,fast,stable and accurate small-sized isolation device was developed for low-to-medium-speed spinning aircrafts,where special requirement has been raised for the isolation between the IMU and the aircraft.The structure design was conducted for the isolation device based on the aircraft IMU measurement principles and the operation conditions according to the design requirements.The numerical model of the electromechanical system was established to study the dynamic performance for the subsequent controller correction design.In addition,the corresponding tests were conducted to evaluate the unspinning performance of the device via a specially designed platform.Results show that the speed error rate of the isolation device was controlled under 1%,as per design requirements.This indicates that the high unspinning performance,high control accuracy and quick response to the sudden change of speed were achieved.This paper provides a novel idea for the in-depth study of the unspinning structure of the isolation device.
