摘要:

针对动力学未知的四轴飞行器,提出了一种自适应自动驾驶仪。为此,PX 4自动驾驶仪的结构进行了修改,以取代反馈和前馈控制器的自适应控制法律的基础上追溯成本自适应控制(RCAC)。本文提供了一个数值研究的性能的自适应自动驾驶仪的四轴飞行器与未知的动态。为了反映先验建模信息的缺乏,所有的自适应数字控制器初始化为零增益。此外,改变四轴飞行器的转动惯量来测试自适应自动驾驶仪的鲁棒性。在所有测试案例中,车辆被命令遵循给定的轨迹,并检查由此产生的性能。

英文摘要:

This paper develops an adaptive autopilot for quadcopters with unknown dynamics. To do this, the PX4 autopilot architecture is modified so that the feedback and feedforward controllers are replaced by adaptive control laws based on retrospective cost adaptive control (RCAC). The present paper provides a numerical investigation of the performance of the adaptive autopilot on a quadcopter with unknown dynamics. In order to reflect the absence of prior modeling information, all of the adaptive digital controllers are initialized at zero gains. In addition, moment-of-inertia of the quadcopter is varied to test the robustness of the adaptive autopilot. In all test cases, the vehicle is commanded to follow a given trajectory, and the resulting performance is examined.
