| 摘 要： | 飞航导弹模型可以处理成一种四层非线性、时变块对角结构，但其中一、二层模型不是仿射型模型，这在控制理论的应用上受到限制。本文应用优化线性理论，对这两层模型进行了仿射型处理，这样就得到了飞航导弹的四层非线性信射型模型。接着，本文提出了玫类非线性系统的变结构控制方法，从而对导弹进行了分层变结构控制器设计。仿真结果表明，所设计的系统具有很强的鲁棒性。

| Abstract: | The mathematical model of an aerodynamic missile can be dealt with a nonlinear time variable block diagonal construction with four layers.But the model of 1 st and 2 nd layer is no affine,which can not be used to the design of a controller easily.By using the concept of optimal linearization,an affine model of 1 st and 2 nd are gotten in this paper.In this way,the four layer nonlinear affine model of the missile is gotten also.Then,a procedure of layer variable structure system (VSS) controller of the missile is proposed in this paper also.The simulation shows the method has good robustness. |
