Backstepping Control Method Based on Disturbance Observer for Unmanned Parafoil Vehicle
摘要
Abstract
A variable-gain backstepping tracking control method based on nonlinear disturbance observer is proposed in order to implement the path tracking for Unmanned Parafoil Vehicle(UPV)in the presence of compound disturbance. A variable-gain backstepping tracking control law is designed against the path tracking error model based on simulation object,and a nonlinear disturbance observer (NDOB)based on second order tracking -differentiator is employed to estimate the compound disturbance and make compensation to the control input,which improved system robustness while ensuring stability. In addition,the controller is applied to UPV planar curve path tracking control. The simulation results illustrate the good robustness of the proposed controller,and accurate tracking ability in desired path in the case of compound disturbance.关键词
