摘要
针对存在风扰和变质量负载扰动的四旋翼无人机轨迹跟踪控制问题,提出了一种基于降阶广义比例积分观测器的动态面模糊滑模控制方法.首先,建立含风扰和变质量负载扰动的四旋翼无人机系统模型;其次,结合四旋翼无人机系统模型设计降阶广义比例积分观测器估计外界风扰;再次,设计动态面滑模控制器,并采用模糊控制模糊化切换增益,以此有效地抑制抖振;然后,通过Lyapunov稳定性证明四旋翼无人机系统的稳定性;最后,通过Matlab-Simulink进行3种控制方法的仿真比较.仿真结果表明,当存在风扰和变质量负载扰动时,该控制方法抗风扰能力更强,稳定性更好,位姿跟踪精度更高.
Abstract
A dynamic surface fuzzy sliding mode control method based on reduced-order generalized proportional inte-gral observer is proposed for the trajectory tracking control of quadrotor UAV with wind disturbance and variable mass load disturbance.Firstly,a quadrotor UAV system model with wind disturbance and variable mass load distur-bance is established.Secondly,reduced-order generalized proportional integral observers are designed to estimate the external wind disturbance in combination with the quadrotor UAV system.Thirdly,the dynamic surface sliding mode controllers are designed and fuzzy switching gains are used to suppress chattering effectively.Then,the stability of the quadrotor UAV system is proved by Lyapunov stability.Finally,the three control methods are compared by Mat-lab-Simulink.The simulation results show that the proposed control method has stronger wind disturbance resistance,better stability and higher pose tracking accuracy when wind disturbance and variable mass load disturbance exist.
