摘　　要：将滑翔制导炸弹横侧向之间各种耦合作用、模型不确定性、内部扰动和外部扰动看成干扰,设计扩张状态观测器对其进行实时估计并加以动态补偿;在此基础上,将对象模型转化为一个积分器串联线性模型,采用测速反馈控制.理论分析及半实物仿真表明,相对于常规PID控制,其控制品质明显提高,具有一定的工程应用价值.in this paper, the coupling action between the lateral channel, model error, interior disturbance and exterior dis- turbance for glide guided bomb are treated as disturbance, then this disturbance is estimated and compensated in real-time, based on this, the plant is transformed into linear series integrator modal. Finally, the tachometer feedback controller is ap- plied on it. Theoretical analysis and semi-physical simulation show the control quality is improved contrasted with PID con- troller.
