摘要
Abstract
A nonlinear disturbance observer based on robust backstepping controller is designed for hypersonic vehicles. Based on backstepping control method,velocity and altitude controllers are designed respectively. The sliding mode differentiators are introduced to obtain the derivatives of virtual control laws,which avoids the explosion of differentiation teens in the traditional backstepping control. In order to enhance the controllers' robustness,a nonlinear disturbance observer is introduced to estimate and compensate the model uncertainties. Reference trajectory tracking simulation shows the effectiveness of this controller in tracking velocity and altitude commands.关键词
