    摘要:

    天線(xiàn)控制單元(Antenna Control Unit, 簡(jiǎn)稱(chēng)ACU)作為船載天線(xiàn)伺服系統的主要組成部分,已實(shí)現ACU雙機熱備份,但在天線(xiàn)跟蹤目標過(guò)程中進(jìn)行切換會(huì )產(chǎn)生較大階躍,可能造成跟蹤目標的丟失,削弱了熱備份的功能實(shí)現。針對該情況,闡述了跟蹤環(huán)和主備機切換的工作原理,分析了產(chǎn)生階躍的原因,提出一種實(shí)現動(dòng)態(tài)跟蹤條件下ACU雙機平穩切換的方法,此方法采用記憶跟蹤的方式進(jìn)行過(guò)渡,實(shí)現切換周期內天線(xiàn)的速度指令不發(fā)生突變,使天線(xiàn)穩定跟蹤,實(shí)驗結果表明,最大誤差電壓不超過(guò)0.08V,有效提高了設備的可靠性。

    Abstract:

    The antenna control unit(ACU) is one of the major constituent parts of shipborne antenna servo system. At present, the dual-server hot-backup technology has been applied to ACU, but the switching between the host and the backup would cause larger step change during the process of dynamic tracking and it could bring about the loss of tracked-target, which would result in the weakness of hot-backup function. To this point, this paper represents the working principle of auto-tracking loop and host-backup switching and analyses the reason of step change. Then an novel approach is presented to realize the smooth switching of ACU under dynamic tracking condition via memory tracking in order to accomplish the continuous output of speed command to antenna within switching period, by which the antenna could track the target stably. The results of experiments indicate that the maximal error voltage is less than 0.08V, and it enhances the reliability of facility effectively.
