| 摘 要： | 针对非线性系统存在建模误差和外界干扰等不确定因素问题，提出一种基于非线性干扰观测器（Nonlinear Disturbance Observer，NDO）在线补偿的轨迹线性化控制（Trajectory Linearization Control，TLC）方法。设计非线性干扰观测器，对不确定因素进行估计，NDO的输出用以设计新的补偿控制律，与TLC方法相结合来消除不确定因素的影响。以赫布斯特机动过程为例进行飞行仿真，并与单纯采用TLC方法的控制性能进行对比。仿真表明，系统能较好地跟踪姿态角指令，有良好的鲁棒性。

| Abstract: | Considering the uncertainties,such as errors in modeling and external disturbances,existed in nonlinear systems,a nonlinear disturbance observer(NDO) is used to estimate the uncertainties,and then its output is integrated with the output of Trajectory Linearization Control(TLC),as a new control law to cancel the unknown term.So,nonlinear systems will attain to excellent performance.Herbst maneuver is simulated for an aircraft mathematics model using this method,and for comparison,the herbst maneuver is also... |
