饋入軌 的英文怎麼說
中文拼音 [kuìrùguǐ]
饋入軌
英文
track feed-
Use energy - based control method to achieve the entry flight control of reusable launch vehicle. the basic concept is to take the energy as primary control variables, reduce the order of the system and design a tracking law to follow a three - dimensional entry trajectory
本文採用基於能量的控制方法實現對航天器再入軌跡的控制，將能量作為獨立參量，從而降低系統的階數，利用線性反饋的方法設計一個跟蹤三維再入軌跡的控制律。The algorithm of strapdown inertial navigation system is also discussed and then use the flight - track generator to give a simulation, since a closed loop feedback integrated navigation system is designed in this paper, and the output of the filter must feed back to the strapdown inertial navigation system, the analysis of the algorithm in strapdown inertial navigation system is important. the scheme to design the trajectory of gps and the simulation of gps constellation are then studied, the simulation of gps constellation is given from the calculation of vernal equinox base on the principle of celestial mechanics, this method of different from other methods given by other paper and is useful to the research of satellite navigation system. a new method to abstract noise modal in integrated navigation system is proved to be useful in practice, this method, which is given by use the principles of stochastic processes, statistics, time series analysis, and system identification, is suitable for the kalman filter in integrated navigation system
如航跡產生器的設計，該航跡產生器是研究組合導航問題的前提，從國外一些研究組合導航系統的文獻中可以看出，設計這樣一個航跡產生器是非常必要的，所以本文自行設計了這樣一個系統；還討論了捷聯慣性導航系統中捷聯解算的方法，並進行了模擬研究，由於在本文設計的閉環反饋式組合導航系統中，對捷聯慣導系統的平臺誤差進行閉環控制，需要將濾波器輸出的校正量反饋到捷聯解算內部，所以必須對捷聯解算進行深入的研究和分析，更何況捷聯解算問題本身也是導航界的一個熱門研究課題；另外，本文還介紹了gps軌道及其星座模擬的設計思想和方案，與以往gps軌道和星座模擬不同的是本文從天體力學中計算春分點開始，逐步進行gps軌道及其星座模擬，這樣的設計方法對從事衛星導航的研究工作是有價值的；還對組合導航中誤差建模方法進行了研究，綜合運用隨機過程、概率統計、時序分析及系統辯識等方面的理論提出了一套適合組合導航卡爾曼濾波的誤差建模方法，並運用實際研究工作中的測量數據對該方法進行了驗證。The author adopts means of systematical theory and total theory, establishes a research path of “ main body action, trade, institutional structure, economy output, research on countermeasure ” pattern, designs a problem ? raised, theory ? analyzed, situation ? researched and example ? applied structure of study transotion mechanism, and fully study the theory and solution of northeast institution mechanism with compare system analysis, math method and evolutionary game theory. first of all, this paper analyzes the basic theory, which serves as the
本文堅持系統分析和均衡分析的分析方法，創建了「主體行為?交易?制度結構?經濟績效?反饋」的分析框架，構建了「問題提出?基本理論分析?現狀研究?理論命題?對策研究」的轉軌機理研究路徑，運用比較制度分析、數學模型和演化博弈制度分析等方法，全面深入地研究東北地區經濟轉軌內在機理的理論和途徑。Then on the base of the computer model, the standard reentry trajectory guidance law is studied, and an approach to obtain the guidance coefficients by modifying the initial value through feedback bias repeatedly is put forward. simulations have proved the feasibility of the method
在這個基礎上，本文對飛船再入標準軌道制導方法進行了研究，提出了一種利用制導參數偏差迭代求解反饋增益系數的方法，並通過大量模擬驗證了此方法的可行性。分享友人
