针对制导航空炸弹的滚转通道，设计了一种具有线性部分变结构控制器。基于弹体模型的时变特性，该控制器首先设计切换函数以确定滑动模态动特性，附加以参数变化范围内的定常模型为对象的线性部分用以控制趋近模态。对某型号制导炸弹设计变结构控制律，仿真结果表明能较好地适应系统的参数变化，提高控制精度，系统具有良好性能。
Aiming at the rolling passage of the guided aerial bomb, a variable structure controller with linear part is designed. Based on the time-varying characteristics of the projectile model, the controller first designs the switching function to determine the dynamic characteristics of the sliding mode, and adds the linear part to the steady model in the parameter variation range to control the approaching mode. Variable structure control law is designed for a guided bombshell of a model. The simulation results show that it can better adapt to the change of system parameters and improve the control precision, and the system has good performance.
