中文拼音 [nìxiàngyājiē]
逆向壓接
英文
reverse bonding-
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。This inverse change has brought enormous pressure to local finance management, with the local self - financing rate ’ s falling, local fiscal especially county and township fiscal swamp becomes much worse, which directly hinders the sustaining, rapid and healthy development of local economy. it becomes a serious challenge and difficult problem during china ’ s reform and development
這種收入比重下降和支出比重增加的逆向變化給地方財政管理帶來了巨大的壓力，地方財政自給率的不斷下降，地方財政特別是縣鄉財政的困境愈演愈烈，直接制約了地方經濟的持續、快速、健康發展，成為我國改革和發展所面臨的嚴峻挑戰和棘手難題之一。Make sure the diaphragm tab and compressor guides are properly located in their body slots by rotating the handle counterclockwise until the stem is in the full up position
通過逆時針方向旋轉手柄，直到閥桿位於完全上升的位置，確保隔膜接頭片和壓縮裝置導架位於閥體上的相應的槽上。This paper make a study of controller on permanent magnetsyn - chronous motor. the permanent magnetsyn - chronous motor has many virtue such as simply structure and simle solidity etc. with this excellence. it has more and more uses in industry and agriculture. the idea of this paper is to control permanent magnetsyn - chronous motor system through vector control. to solve the problem of pid regulator, we use the fuzzy control and self adaptive pid
本文設計的思路是採用轉子磁通定向的矢量控制技術，主電路採用spwm和交-直-交電壓型逆變器，其中spwm採用sa4828晶元直接產生，在控制器的實現方面，採用了tms320lf2407型dsp晶元作為主控板cpu ，實現了電流、轉速雙閉環的控制系統。The formula for mach number has been optimized with least - squres solution, thus the precision of a polynomial of power of 5 is better than that of 9. 2. after the solving of angle of attack and angle of sideslip, the theory of general inverse of matrix is used to simplify the nonlinear equations and to calculate the total pressure and the modified dynamic pressure ratio. these two parameters together with the angle of attack and angle of sideslip contain enough information to work out the dynamic pressure and static pressure
其中包括: 1 .應用最小二乘法，對馬赫數的泰勒求解公式進行優化，優化后的求解公式採用5次多項式即可在精度上優于原有的9次多項式，可以提高運算速度; 2 .提出應用廣義逆矩陣簡化非線性方程組:在已經求解出迎角與側滑角的前提下，直接從原始的壓力向量中提取出總壓，並且提出了動壓修正比的概念。分享友人
