基于某反坦克导弹自动驾驶仪设计研究

The Design of a Antitank Missile's Verticalchannel Autopilot Based on Analytic Method

由于某反坦克导弹作战射程小、时间短、打击精度高,对控制系统响应时间和控制精度要求很高,设计合适的自动驾驶仪是反坦克导弹控制系统设计的关键。传统时域频域设计方法对经验依赖性强,对此,建立了某反坦克导弹控制模型,采用双回路结构和解析法设计了导弹纵向通道控制参数,通过调节增益穿越频率参数来调节控制系统的响应时间和稳态误差,得到相关的控制系统设计参数,进而得到俯仰通道的控制率。通过仿真可以看出该纵向通道自动驾驶仪具有响应时间短,控制精度高的特点。改进的设计方法简单可靠,可为其它型号导弹控制系统的设计提供依据。

Antitank missile requires that control system has fast response time and higher control precision, because of the short flighting range ,time and striking accuracy. This paper built a control model . Dual -loop structure and analytic method were used to design the longitudinal channel of vehicle attitude control system parameters. The gain gross - over frequency was adjusted to change response time and steady - state error of the control system. And the control rate of longitudinal channel was obtained. It can be seen that the longitudinal channel of autopilot has shorter response time and higher control precision. This design method is simple and credible,it can be a reference to other missiles＇ design of control.
