Compared with traditional mechanical and optic gyros, hrg has such advantages as no high speed circumvolving or moving parts in structure, no warm - up time and short start - up time, wide signal band in frequency, low excursion noises, great endurance in over loading, nuclear radiation and short time power off, small bulk, light weight, low power cost and long life, which is suitable for space applications
與傳統的機械陀螺和光學陀螺相比,半球諧振陀螺具有如下優勢:結構上無高速轉子、無活動部件;不需預熱,啟動時間短;信號頻帶寬,漂移噪聲低;能承受大的機動過載;抗核輻射,並可經受短時間電源中斷的影響;體積小,重量輕,功耗低,壽命長,非常適合空間應用。With the increasing initial orientation angle and length - width ratio, the drifting distance, the fluctuation of the orientation angle, lateral drifting velocity and rotation velocity all increase, while the final settling velocity decreases with the increasing length - width ratio
初始取向角和長寬比增大,則粒子的橫向漂移以及取向角、側向漂移速度和轉動角速度的振蕩幅度都增大;同時隨著長寬比的增大,粒子的沉降速度相應減小。Lots have been done concerning repairable m / g / 1 queuing systems and many important results have been gotten. in this paper we make a further research about this system. by setting a n - threshold in the queuing we considered repairable m / g ( m / g ) / 1 queuing systems with two service speeds changing according the number of the customers in the system. we separately make a particular deep discussion to different disciplines of the service speed change
當今對可修m g ( m g ) 1排隊系統已作了大量研究,獲得了許多漂亮的結果;本文對此作了進一步的推廣,通過對系統中的顧客數設置門限n值,首次考慮研究了服務臺具有兩種服務速度且會隨著系統中顧客數的多少而發生轉移地可修m g ( m g ) 1排隊系統,就服務速度的不同轉變規則分別進行了詳細深入的討論。By means of temporary stability of combining drift coefficient of angle sensor and through missile rotating two - position measurement, measuring rotating angle between the two positions by vertical sensitive axis x, and sensing the changes of ground velocity component between the two positions by horizontal sensitive axis and z, the position of the component is determined to realize the azimuth alignment before launch of tactical missile
角敏感元件漂移系數具有短期穩定性,通過轉彈前後兩位置對組合的測試,垂直敏感軸計測轉彈過程中兩位置之間的轉角,兩水平敏感軸敏感計測地速分量在前後兩位置的變化,由此計算出部件當前所在方位,從而實現戰術彈射前的方位對準。Specific issues examined are : compensation for the variation of the stator resistance, the offset error of the dc bus voltage, the voltage error generated by the forward voltage drop the dead time of the switches, improvement of the steady state performance, and the speed sensorless control for the pmsm dtc drive system are of major concern in this thesis
定子電阻變化,直流母線電壓漂移,開關器件反向相電壓降、逆變器死區時間引起的電壓誤差的補償,提高系統穩態運行性能以及永磁同步電機直接轉矩控制的無速度傳感器運行方案等問題都是本文研究的重點。轉矩的快速響應是直接轉矩控制演算法的一個卓越的性能。In the process of single fiber sedimentation, it is steady that the fiber axis orients horizontally. the terminal sedimentation rate and the lateral shifting rate increase with the particle aspect ratio. the fiber with the aspect ratio of about 2. 8 rotates fastest to the stable location
對于單根纖維的沉降,其穩定取向是軸線與重力方向垂直的方向;纖維的沉降速度隨長徑比的增加而增加,但趨勢變緩;纖維的橫向漂移隨長徑比增加而增加;長徑比在3左右的纖維,旋轉到穩定取向的速度最快。Reasons of imaging excursion of two rotating mirror high speed cameras used simultaneously are discussed, and the influence to images are analysed according to the theories and experiments, such as the signal drift of the magnetoelectric sensor and improperly operating etc
