Abstract

During the Vertical Take-Off and Landing (VTOL) of a rotorcraft, there is a high risk of instability and safety incidents due to the possibility of one side of the landing gear making initial contact with the ground, particularly under extreme environmental conditions and maneuvers. Furthermore, the varied performance of adaptive landing gear necessitates a landing control approach that specifically targets both sides of the adaptive landing gear. This study proposes a method that regulates the landing gear first touchdown side through an impedance controller to guarantee the stability of the rotorcraft and then tilts the landing gear toward the rear landing leg side, followed by a soft and smooth landing through the rear landing leg. This approach accomplishes steady adaptive VTOL of the rotorcraft. The fall vibration test results demonstrate that the adaptive landing gear system with impedance control has excellent adaptive landing functionality, which can handle not only landing on uneven ground at various points but also cope with different ascent rates and ground friction during stable takeoff/landing.

基于阻抗控制的防侧翻自适应起落架技术研究

在旋翼机的垂直起飞和着陆（VTOL）过程中，由于一侧起落架有可能与地面发生初始接触，因此极有可能出现不稳定和安全事故，特别是在极端环境条件和机动情况下。此外，自适应起落架的性能各不相同，因此需要一种专门针对自适应起落架两侧的着陆控制方法。本研究提出了一种方法，即通过阻抗控制器调节起落架先着陆的一侧，以保证旋翼机的稳定性，然后将起落架向后着陆腿一侧倾斜，再通过后着陆腿实现软着陆和平稳着陆。这种方法实现了旋翼机稳定的自适应 VTOL。坠落振动测试结果表明，带阻抗控制的自适应起落架系统具有出色的自适应着陆功能，不仅能在不同点的不平整地面上着陆，还能在稳定起飞/着陆过程中应对不同的上升速率和地面摩擦。
