Abstract

This paper presents an example of a PID controller applied to a 2-dimensional rotorcraft landing gear with two DOF (degrees of freedom), as well as the design of the landing gear dynamic model. The focus of this work is to maintain the landing spot to prevent the landing gear from skidding sideways on the ground, while adapting to different ground conditions. A nonlinear model for the landing gear dynamics formulated by solving Lagrange equation, is described in detailed, as well as the angle generation equations to provide reference signal to the system. The simulation results based on different surface conditions are presented.

旋翼机起落架在不同地面条件下的控制
本文给出了将PID控制器应用于二自由度二维旋翼机起落架的实例,并给出了起落架动力学模型的设计。这项工作的重点是保持着陆点,防止起落架在地面上侧滑,同时适应不同的地面条件。详细描述了求解拉格朗日方程建立的起落架非线性动力学模型,并给出了角度生成方程,为系统提供参考信号。给出了不同表面条件下的仿真结果。
