直接力/气动力复合控制拦截弹的飞行控制系统设计

Modeling of Flight Control System for Blended-control Interceptor

推导了气动力与力矩式直接力复合控制拦截弹弹体的数学模型,用气动力控制与直接力控制并行的方式初步设计了拦截弹的飞行控制系统,最后推导出复合控制拦截弹的飞行控制系统的传递函数,并分析了拦截弹分别采用复合控制和空气动力控制时的飞行控制系统时间常数。在此基础上进行拦截弹末制导精度的仿真,验证了复合控制方式比气动力控制更为有效。

The mathematical models of the interceptor controlled by blending the aerodynamics control with reaction jets control are studied. The flight control system（FCS） of blended-control interceptor is designed simply by parallel control fashion; last, the transfer function of FCS is established, and then analyze time constant of FCS for blended-control interceptor is smaller than that of aerodynamic-control interceptor. Basing on these terminal guidance accuracy is simulated. and blended-control is superior to aerodynamics control.
