全驱动三轴可倾转旋翼飞行器位姿解耦控制研究
Research on decoupled position and attitude control of a fully actuated tricopter with tiltable rotors
摘要
Abstract
Traditional tricopters suffer from coupling between position and attitude control due to the number of control inputs being fewer than the degrees of freedom,which limits maneuverability.To address this issue,a fully actuated tricopter with tiltable rotors featuring a coaxial dual rotor design is proposed.This design enables decoupled control of position and attitude,thereby broadening the application scenarios for multi-rotor aircraft.First,the configuration of the aircraft is designed.A dynamic model of the aircraft is established using Newton-Euler methodology.A control allocation scheme for the aircraft is devised employing variable substitution.To accomplish substantial alterations in attitude angle,unit quaternions are employed for representing the orientation.A cascaded PID control method is adopted to design the position and attitude controllers for the aircraft.Finally,a simulation platform is built in Simulink,and a real-machine validation platform is set up based on the Ardupilot flight control system.Experimental results indicate the fully actuated tricopter with tiltable rotors achieves decoupled control of its position and attitude,enabling maneuvers that can't be achieved by underactuated aircraft,such as hovering with attitude changes and trajectory tracking with a fixed attitude.关键词
