针对激光制导炸弹侧向控制通道为导引回路的一部分，同时其参数随投放高度和投放速度发生很大变化等特点，给出了一种线性时变系统模型参考变结构控制器的设计方法，并进行了仿真研究，结果表明，所给方法性能优良。

In the control system of laser guided bombs，the control channel is a part of the guidance loop，and its parameters vary with the altitude and velocity of bomb — release. Based on these fea?tures ,a design scheme of model reference variaoie structure controller for a linear time-varying sys?tem is proposed. A controller for some type of laser guided bomb is designed, and simulation results showed satisfactory performance of the proposed method.
