电流调制
Examples
- Novel current modulation approach for the vector control of mc - pmsm system
一种减少矩阵变换器共模电压的空间矢量调制法 - Beam current modulation
束电流调制 - Adopting rotor field - oriented vector control methods , through which make the stator and the rotor magnetmotive forces can be kept orthogonal all along during operation of the bldcm , combining hysteresis current modulation ' s current control advantage and space voltage vector modulation ' s torque ripple attenuation advantage , then designing a sort of bldcm hysteresis current svpwm control method
摘要研究采用转子磁场定向的矢量控制方法使无刷直流电动机定、转子磁势矢量始终保持正交，结合滞环调制电流控制和空间电压矢量调制，设计了无刷直流电动机滞环电流svpwm控制方案。 - Adaptive modulation can also control quality of service according to transmitted information type and greatly increase capacity of system . the data frames in adaptive modulation communication system must be redesigned . because the sender must tell the receiver the current modulation mode by some bits in the data frame and the receiver must gain the current channel condition from the data frame in order to control its modulation mode and symbol rate
因为发送方须通过数据帧中的某些比特来通知接收方当前的调制方式和符号速率；同样，接收方也须从数据帧中某个域的比特流来获得当前的信道条件信息，从而去控制其调制方式及符号速率。 - Second , the imaging model built here has taken into account the tilt modulation , the hydrodynamic modulation , and current modulations of radar cross section . consequently , it has realized the imaging simulation of four kinds of wakes with the same imaging model . third , the orbital velocity of ocean wave was considered as the basic dynamic factor , and the imaging model calculates the influence on raw data by the wave m ovement according to the orbital velocity
该模型的主要特点是： ( 1 )它采用了三尺度复合表面模型的思想来计算海面的电磁散射，考虑了中等尺度波对纹波的进一步调制作用，弥补了传统双尺度模型的不足； ( 1 )它考虑了海浪的倾斜调制作用、流体动力调制作用和流场对雷达截面的调制作用，实现了用统一的仿真模型对四种舰船尾迹特征进行成像仿真； ( 3 )它把海面长波的轨道速度作为基本的动态成分，并依此来考虑海面运动对sar回波信号的影响。
