预定增益理论在导弹飞行控制系统中的应用

Application of Gain Scheduling on Flight Control System of Missile

针对导弹在飞行过程中动力学特性大范围变化的特点,以俯仰通道为例,运用预定增益控制理论设计导弹飞行控制系统,即利用导弹空气动力学特性和导弹某些特征参数的强相关性来调整控制器参数,确保导弹在要求的飞行条件下满足稳定性和动态品质。最后通过仿真验证了所设计的控制器满足性能要求。

Based on the aerodynamic characteristics of missiles which vary in great range, we use gain scheduling control theory to design the flight control system, i.e. adjust the parameter via the relativity between the aerodynamic characteristics and some character parameter of the missile, in order to satisfy the stability and the dynamic quality in the flight process of the missile. The result of the simulation shows that the control system satisfies the performance require.
