基于最优控制的自动驾驶仪结构研究

Autopilot Topologies Research Based on Optimal Control

基于最优控制的方法研究了自动驾驶仪的设计,并建立起导弹纵向自动驾驶仪经典控制设计和最优控制设计之间的联系。文中主要研究不同三回路驾驶仪结构,并最终基于鲁棒性找出最优的结构。通过基于最优控制的理论研究可以得知,不同的三回路驾驶仪结构,在相同性能的最优控制下可得到等价的闭环响应,但却具有不同的开环特性。

Autopilot design was researched based on optimal control. The connection between classical and optimal control for missile longitudinal autopilot was established. The focus of this paper is to examine three loop topologies and determine the best in terms of robustness. It＇s shown that there is transformation that can provide equivalent closed loop properties for different topologies, but the open loop properties will be different.
