摘　　要：防空导弹在作大机动飞行时，弹体气动参数剧烈非线性变化。在分析弹体特性的基础上，采用积分变结构控制（IVSC）方法设计了侧向过载控制器，通过积分稳定控制回路，保证了高精度稳态传输比，利用变结构控制回路增强控制系统对弹体参数摄动的鲁棒性。仿真结果表明：设计的控制器稳态精度和鲁棒性能指标优良。In the process of an anti-aircraft missile with highly maneuverable flight, nonlinear variation of aerodynamic parameters is happened. On the basis of analyzing the airframe speciality, an overload controller with integral variable structure control method is designed, and the transmit ratio of high precision steady state by means of integral control loop is ensured. The robustness of the control system by means of the variable structure control loop is increased. The results of simulation illustrate that the designed overload controller can achieve the accurate servo tracking and is fairly robust to plant parameter variations.
