電子掃描雷達系統(tǒng)中天線方位角和仰角的魯棒控制器設計
發(fā)布時間:2020-12-22 04:50
本研究的目的是設計一種用于天線電子掃描雷達系統(tǒng)(AZ-EL)俯仰角和方位角的控制器,這兩個角度是控制雷達跟蹤目標時的主要特征。然而,由于整個系統(tǒng)遭受諸如高速運動的風之類的干擾,在實際跟蹤目標的時候仍然存在挑戰(zhàn)。此外,由于慣性矩因素,在負載變化時系統(tǒng)性能降低。以上是設計控制器必須知曉的主要內(nèi)容,以及為什么系統(tǒng)必須對所有的這些變化具有魯棒性,本文致力于對AZ-EL雷達底座的位置進行高效精確控制,這也驗證了使用魯棒控制器的正確性,因為其最重要的優(yōu)點是對參考輸入的變化不敏感?刂破鲗⒄{(diào)節(jié)雷達基座執(zhí)行器的輸出位置。本文選取永磁同步電動機(PMSM)進行控制,因為其是滿足控制目標的最佳選擇。通過定義合適的滑動平面并計算相應的輸入值來設計魯棒滑?刂。在設計的控制器調(diào)節(jié)PMSM電機的電流時,同時雷達調(diào)整跟蹤位置,通過對電機模型仿真,計算和比較控制器的算法來對非線性特征進行更精確控制。最后,在實時仿真中對控制器的性能進行了測試。將參考方位和仰角數(shù)據(jù)隨機地作為跟蹤目標,從而證明了所提出的方法用于控制雷達基座的有效性。該項目在三維實時仿真環(huán)境下處理系統(tǒng)的動態(tài)特性和控制器的設計。為此,我們需要建立緊密的關聯(lián)...
