本文主要讨论了战术导弹自动驾驶仪的自适应控制设计。文中以简化的导弹自动驾驶仪的差分方程为控制对象,采用衰减记忆最小二乘法直接识別弹体的时变参数,再应用极点配置控制方法计算出反馈控制量,实现系统的闭环自适应控制。数字仿真结果表明,在改善象自动驾驶仪这样的随机控制系统的性能方面,极点配置自校正控制是一项行之有效的方法。
This article mainly discusses the adaptive control design of tactical missile autopilot. In this paper, the simplified missile autopilot differential equation is taken as the control object, the time-varying parameter of projectile is directly identified by the least square method of attenuation memory, and then the pole control method is used to calculate the feedback control volume to realize the closed-loop adaptive control of the system . The numerical simulation results show that the pole placement self-tuning control is an effective way to improve the performance of stochastic control systems like autopilots.
