摘要:

本文提出几种基于微分平坦性性质的非线性控制策略,用于四旋翼系统的轨迹跟踪。其创新性体现在两方面:首先,提供一个能够实现状态和输入全参数化的四旋翼动力学平坦输出;其次,B样条对平坦输出的特征化及其性质允许在满足航点约束条件下生成最优轨迹。此外,本文还提出了几种基于计算扭矩控制和反馈线性化的控制策略,并进行了比较。通过广泛的仿真结果分析,详细阐述了每种控制策略中平坦性带来的优势。

英文摘要:

This paper proposes several nonlinear control strategies for trajectory tracking of a quadcopter system based on the property of differential flatness. Its originality is twofold. Firstly, it provides a flat output for the quadcopter dynamics capable of creating full flat parametrization of the states and inputs. Moreover, B-splines characterizations of the flat output and their properties allow for optimal trajectory generation subject to way-point constraints. Secondly, several control strategies based on computed torque control and feedback linearization are presented and compared. The advantages of flatness within each control strategy are analyzed and detailed through extensive simulation results.
