Depend on the comprehensive analysis and study of the structure , principle , and exterior characteristic of the motor , through the methods of system modeling and digital simulation analysis , two kind of control device that work for the low voltage ( lvdc ) and the high voltage ( hvdc ) in avigation are researched respectively . point to the control technique of close - loop speed stabilization at a limited adjustment speed range , we bring out the close - loop speed control method that using the rotor position sensor indirectly measure the speed of the motor 在全面分析了稀土永磁無刷直流電動機的結構特點、工作原理、運行方式以及外部特性的基礎上,通過系統建模和數字仿真分析,分別針對航空低壓直流( lvdc )和高壓直流( hvdc )兩種電動機構用永磁無刷電動機,在小范圍轉速連續調節下的閉環穩速控制技術進行了詳細理論研究,提出了利用轉子位置傳感器信號間接測量電機轉速進行電機轉速閉環穩速控制的策略。

Combined with the foundation research ( avigation science fund 04d52032 ) ” study on cfar detecting expert system base on clutter tracking ” . this paper study the fractal technic and snake algorithm on the application of clutter tracking . it proved that the method was effective by the algorithm which adapt to the real and simulant clutter data 本課題結合航空科學基金“基于雜波跟蹤融合的恒虛警檢測專家系統研究” ,研究分形技術和snake算法在雜波跟蹤中應用,設計了相應的算法,通過分析真實數據和仿真數據驗證了算法的有效性。

Vsp is both a pivotal tache in logistic distribution optimization and indispensable in electronic commerce . it can increase logistic economic benefit and realize logistic rationalization . the systemic study on the theory and method of vsp is the base on the growth of logistic intensivism , the establishment of modem chain of command , the development of its and ec . now , the problem is not only applied to the field of auto transportation , but also to ship avigation communication electricity industry management computer application etc . the algorithm has been applied into many combinatorial optimization problems such as the trainman ' s shift arrangement in avigation the optimization design of cargo arrangement in ship company 對貨運車輛進行調度優化,可以提高物流經濟效益、實現物流科學化。對貨運車輛調度優化理論與方法進行系統研究是物流集約化發展、建立現代調度指揮系統、發展智能交通運輸系統和開展電子商務的基礎。目前,問題的形式已有很大發展,該問題以不僅僅局限于汽車運輸領域,在水運、航空、通訊、電力、工業管理、計算機應用等領域也有一定的應用,其算法已用于航空乘務員輪班安排、輪船公司運送貨物經過港口與貨物安排的優化設計、交通車線路安排、生產系統中的計劃與控制等多種組合優化問題。

Accelerometer is the main inertia measurement device of inertia measure - ment and navigation system , it ’ s mainly used to measure the acceleration of carrier , and we can get the velocity and displacement of carrier from acceleration , so it ’ s wildly used in spaceflight , avigation , navigation and other fields , the capabilities of accelerometer are of the key function in the whole system 加速度計是慣性測量和導航系統的主要慣性元件之一,主要用于測量運載體的加速度值,而通過加速度又可以得到運載體的速度和位移,所以被廣泛應用于航天、航空和航海等領域,其性能的好壞在整個系統中起著關鍵性的作用。

In contrast to traditional synchronous motor of electrical excitation , permanent - magnet synchronous motor ( pmsm ) has more advantages , especially the occasion that requires high precision of control and high reliability , such as avigation , numerical control machine tool , processing center , robot and so on . in addition , it plays an important part in ac motor in modem times 與傳統的電勵磁同步電機相比,永磁同步電機具有許多優良的特性,尤其是在要求高控制精度和高可靠性的場合,如航空、數控機床、加工中心、機器人等方面獲得了廣泛的應用,在現代交流電機中也占有舉足輕重的地位。
