sine table meaning in Chinese

正弦表

Specification for metric sine bars and sine tables excluding compound tables
米制正弦规与正弦台
Due to the symmetry of sine waveform , the logic resource of cpld is saved greatly by a particular searching way of the sine table
利用正弦波的对称性，采用一种特殊的查表方法，大大节省了cpld的资源。
The standard sine waveform is generated by looking up the sine table , and the triangular carrier waveform is produced by a reversible counter
Spwm信号的产生采用正弦波与三角载波比较的方法，标准正弦波采用查表法实现，三角载波用可逆计数器实现。
This paper put forward a method of using amending sine value in the spwm sine table . this method can correct the distortion of the output voltage waveform , which resulted from the dead time used to the voltage type whole bridge main circuit . the inverter system adopts digital fuzzy controller with feed forward correction and which proportion coefficient and integral coefficient is changeable , so dynamic response is improved
本文提出了一种采用修补spwm正弦表值的方法，用以改善电压型全桥逆变主电路因上下桥的功率器件切换时先关断后导通的死区时间而引起的输出电压波形畸变；逆变系统采用带前馈校正的变比例变积分系数的模糊控制器，提高了系统的动态响应指标；系统设计了完善的保护措施，并具有市电电网的故障诊断功能。
