基于改进ESO和反步法的四旋翼轨迹跟踪控制
Trajectory tracking control of quadcopter unmanned aerial vehicle based on improved ESO and backstepping method
摘要
Abstract
To solve the trajectory tracking control problem of a quadrotor unmanned aerial vehicle(UAV)in the presence of uncertainties such as multi-source disturbances and system parameter perturbations,a robust trajectory tracking strategy based on an improved extended state observer(ESO)and backstepping control method was proposed.An improved ESO was designed,which was based on an optimized function.This ESO consolidated internal uncertainties and external disturbances of the quadrotor UAV system into a total system disturbance term,and provided real-time estimates to compensate for the control input.Subsequently,based on the semi-coupled nature and strict feedback structure of the quadrotor UAV system,the dynamic model of the UAV was decoupled into an inner-loop attitude subsystem and an outer-loop position subsystem.The backstepping method was used to design control laws for both the inner and outer loops,ensuring rapid convergence of the system.Simulation experiments demonstrated that the proposed improved state observer exhibited stronger error-following capabilities,and the designed backstepping anti-disturbance controller possessed better trajectory tracking ability and robustness.关键词
