Flight simulator plays an important role in hardware - in - the - loop simulation , and a high - quality simulator is critical in developing a high - performance aircraft . flight simulator is very important to the aeronautics and astronautics industry . so , the study of advanced control methods for flight simulator ’ s system is of great social and economical benefit 飛行仿真轉(zhuǎn)臺是飛行器半實物仿真的關(guān)鍵部件之一,其品質(zhì)的優(yōu)劣直接關(guān)系到仿真試驗的可靠性和置信度,是保證飛行器精度和性能的基礎(chǔ),在航空航天工業(yè)和國防建設(shè)中具有重要的意義,所以對轉(zhuǎn)臺系統(tǒng)中控制方法的研究具有很大的社會效益和經(jīng)濟效益。
Flight simulator plays an important role in hardware - in - loop simulation , and a high - quality simulator is critical in developing a high - performance aircraft . this paper focuses on the performance improvement , it develops the controller of three axises and adjusts the control parameters in frequency - domain . it also concerns about some factors that influence the low - speed performance and draws some conclusions about the key points of performance improvement 本論文針對轉(zhuǎn)臺的品質(zhì)整定,基于頻域法設(shè)計與實現(xiàn)了轉(zhuǎn)臺三軸的控制器,在頻率域內(nèi)整定了轉(zhuǎn)臺的動靜態(tài)品質(zhì),并對整定過程中的問題和現(xiàn)象作了詳細的分析和研究,提出了轉(zhuǎn)臺品質(zhì)整定的關(guān)鍵點和注意點。
In high - performance aircraft the pilots are vulnerable to ci because of some of the aircrafts " characteristics , which include high sustained + gz ( hsg ) acceleration , high rate of onset and high angular acceleration etc . so it has all the while been attached much importance to the studies on the mechanism of ci and the preventing and overcoming method of ci by the researchers in aviation medicine field 目前以f - 16 、蘇- 27為代表的高性能戰(zhàn)斗機,其所具有的持續(xù)高加速度( + gz ) 、高加速度增長率、高角加速度的特點更易導(dǎo)致飛行中科里奧利錯覺的發(fā)生,嚴(yán)重危害飛行安全。因此,對科里奧利錯覺的機理及預(yù)防與克服研究在航空醫(yī)學(xué)中一直受到人們的重視。
