摘要
针对具有反作用射流和推力矢量导弹的非线性和参数不确定性严重的特点。提出一种鲁棒变结构动态逆控制方法。首先应用动态逆控制对被控对象近似线性化，再通过变结构原理分析模型不确定和外部干扰情况下系统的鲁棒性，在考虑导弹各个环节非理想因素的情况下，针对某型导弹进行了全耦合状态下三通道联合仿真，证明了方法的有效性。
For missiles employing blended aerodynamic control and reaction-jet control system, model uncertainties and nonlinearity lead main design difficult. An robust approach combined dynamic inversion with variable structure method （VSM） is proposed to design a missile autopilot. First, dynamic inversion control law is used to linearize object approximately. Secondly, the system robustness is augmented by sliding model variable structure theory. Finally, simulation tests are made under true condition, and the results demonstrate the efficiency and advantages of the proposed method.
