激光制导炸弹滚转通道的滑模变结构控制

VARIABLE STRUCTURE WITH SLIDING MODE CONTROL FOR THE ROLL CHANNEL OF LASER GUIDED BOMBS

针对激光制导炸弹的滚转控制通道的时变特性，设计了一种滑模变结构控制器，利用系统在滑动模态上的一致鲁棒性使弹体在各工作点上都具有良好的特性。该控制器具有线性部分用以控制趋近段的动态特性，用滑动模态来保证系统在终态的特性。仿真结果表明该控制器具有良好的性能。

Presents a method of variable structure control with sliding mode forthe roll channel controller of laser guided bombs. The scheme is based on the invariance of sliding mode with respect to system perturbations and external disturbances. The linear part is attached to the variable structure control to dominatereaching mode. A controller for some type of laser guided bombs is designed, withthe simulation results showing the effectiveness of the proposed method.
