对力反馈在航空中的应用进行综述,主要涉及无人机遥操作和飞行安全性两大领域。首先,为了解决无人机所捕获的图像信息在分辨率、动态范围、视野等方面的不足,力反馈技术逐渐被引入,并得到了初步应用。起初没有考虑地面控制站与无人机之间的通讯时延问题,力反馈与小波变量的结合能有效地解决时延问题,但操纵负荷仍然很大,继而力刚度反馈技术被提出。其次,飞机执行器速率的限制易导致飞行员诱发的震荡危及飞行安全,为了有效地抑制这类震荡,智能提示和智能增益技术被提出。通过上述的分析和探讨,说明力反馈技术在航空中的研究与应用具有重要的意义。
The review of the application of force feedback in aviation mainly involves the two fields of UAV teleoperation and flight safety. First of all, in order to solve the shortage of resolution, dynamic range and visual field of image information captured by UAV, force feedback technology is gradually introduced and has been initially applied. At first, the problem of communication delay between ground control station and UAV was not considered. The combination of force feedback and wavelet variables can effectively solve the delay problem, but the control load is still very large. Then the force stiffness feedback technology was proposed. Second, the limitation of the aircraft actuator speed easily leads to pilot-induced vibration endangering flight safety. In order to effectively restrain such shocks, intelligent prompts and intelligent gain techniques are proposed. Through the above analysis and discussion, the force feedback technology in the aviation research and application is of great significance.
