Estimation of scale parameter of normal distribution under q - symmetric entropy loss function
對稱熵損失函數下正態總體刻度參數的估計 -
According to the relationship of the angle of the maximum torque and the q axis, the reluctance torque for salient pmsm is made full use of and the sator current amplitude is reduced by a large percentage, so that the system robustness is greatly increased. at the speed loop, this paper presents a single value model algorithmic control strategy which is the simplied form of normal model algorithmic control and has less computation work than the latter, so the real - time performance is very good
對于嵌入式pmsm ，根據在電流幅值一定的條件下最大輸出轉矩與（為等效電流矢量和q軸之間的相位角）之間的關系，將磁阻轉矩轉換為輸出轉矩從而提高了輸出轉矩，改善了系統的控制性能；在速度環採用單步模型演算法控制，其計算量比較少，提高了系統的實時性和魯棒性。 -
At present the manufacture of surface acoustic wave use the technology of the final submicron. a series of the devices of low insertion loss, high q saw rayleigh surface acoustic wave resonators or stws that insertion loss has less than 5db, load quality factor ( ql ) is more than 1000 on the quartz piezoelectric with zero of first temperature factor in the research. these difference frequencies are 60mhz, 280mhz, 739mhz and 1ghz of normal frequency and at also surface acoustic wave. using 1. 25db noise factor amplifier, careful design curcuit, good setting printed curcuit board, and using the 1ghz surface transverse wave resonator as frequency element, researching the low phase noise surface acoustic wave with sideband phase noise near ? 120dbc / hz deviating 1khz on carrier, spurious suppress with 80db
