闭环控制算法在导弹地面测试发控系统中应用的研究

Closed-loop Control Algorithm at Missile Organically Testing and Launching System Suffer Applied Research

在导弹地面测试发控系统进行测试时,要求转电前由地面电源对弹上各设备供电,为保证弹上各设备正常工作,弹上母线电压需保持在某一稳定值。为此,基于西门子S7-200可编程控制器,选用可调电源,应用PID算法进行闭环调节,实现了对地面可调电源电压输出的稳定控制。提出了PID闭环控制的工作原理和实现方法,在地面试验中取得了百分之百准确的效果。

For ensure bomb upper each equipment normal working,bomb upper busbar voltage require kept at one stable value against to.Wherefore repose Siemens S7-200 PLC,choose to use adjustable power supply,application pid algorithm proceed closed loop adjustment,realize know clearly over the ground adjustable power supply voltage export stable control to.This paper introduces pid closed-loop control implementation method and step,these means under ground on trial procure know clearly satisfied.
