战术导弹的一种自校正控制

本文探讨自校正控制理论在战术导弹控制中的应用。采用一种渐近的最小方差自校正控制方案设计导弹自动驾驶仪回路。该方案通过设计自校正控制器的极点和可调增益,使控制器稳定,并能兼顾闭环系统的动态特性,也可使输出方差趋于最小。在两种参考输入信号情况下进行仿真,结果表明,与经典控制情况相比,该方案具有较强的抑制干扰能力,能克服参数变化对系统控制性能的影响,提高了系统的跟踪性能。

A SELF-TUNING CONTROL SCHEME OF TACTICAL MISSILE

In this paper, the application of self-tuning control ther oy to the tactical missile is discussed. An asymptotic minimal variance self-tuning control scheme is used to the circuit of autopilot. By designing the poles and tunable gains of the controller, this scheme can make the controller stable and improve the dynamic properties of the whole closed-loop system. It can also make the output variance minimal. The Simulation under two kinds of reference input signals shows that, compared with the situation of classical control, this scheme has more power to resist the disturbance and it can overcome the influence of the parameter change to the performance of control system and improve the tracking performance of the system.
