【摘要】 针对飞机大机动飞行时存在的模型气动参数不确定性和外界扰动等影响因素,提出了一种基于反步法的鲁棒自适应滑模控制方法。基于反步的思想,适当选取李亚谱诺夫函数回馈递推得到不确定参数自适应律,并在最后一步结合线性滑模设计滑模控制器。对某飞机六自由度模型的大机动仿真验证了该方法的有效性。更多还原

【Abstract】 A robust adaptive sliding mode controller based on backstepping is proposed for high maneuvers flight regarding model parameters uncertainties and unknown disturbance. The uncertain parameters adaptive law is obtained recursively via an appropriate choice of Lyapunov function based on backstepping procedure,and sliding mode controller is designed with the linear sliding mode in the last step. The high maneuvers flight simulation results for non- linear 6- DOF aircraft model show the effectiveness of the control method.更多还原
