机载刚性支撑式快速控制反射镜设计

设计了一款紧凑型刚性支撑式快速控制反射镜(FSM),以适应机载运动平台的高振动、大冲击和高低温等恶劣工作环境。考虑机载FSM的工作需求, 分别对FSM的支撑轴系、驱动元件和测角元件等进行设计与选择。针对刚性支撑轴系设计了轴系间隙调整机构, 提高了FSM系统的轴系精度, 进一步增大了FSM的承载能力; 针对机载FSM研制了专用小尺寸微位移测量传感器, 通过将4个传感器非轴线对称布置, 并利用二次差分的方式实现反射镜位置的实时监测, 进一步减小了FSM系统的体积, 提高了它的测量精度。最后, 对机载FSM的控制带宽和指向精度进行了实验检测。结果显示: 所设计的FSM系统控制带宽约为110 Hz, 方位指向误差不超过3.4″, 俯仰指向误差不超过3.8″, 表明所设计的FSM控制系统稳定、响应速度快、指向精度高, 满足机载运动平台的应用要求。

Abstract

A compact Fast Steering Mirror(FSM) with a rigid support structure was designed for adapting to the great vibrancy, impact and high-low temperature conditions of an airborne platform. The support shafting, actuators, angle measurement elements of the FSM were designed and selected respectively on the basis of design requirements of the FSM. Then, a device to adjust shafting clearance was designed to improve shafting precision and provide additional supporting for mobile parts of the FSM. The special grating displacement sensors with small sizes were designed and four grating sensors were placed on the diagonal symmetrically to measure the position of the mirror by quadratic average of each measuring result, which reduces the volume of the FSM, improves its measuring precision, and removes the influence of clearance in the shaft direction on measuring results. Finally, the control bandwidth and pointing precision of the FSM for the airborne platform were tested, and the results show that the designed FSM offers the control bandwidth about 110 Hz, azimuth pointing error less than 3.4″ and the pitch pointing error less than 3.8″, which satisfies application requirements of vehicle platforms.
