scan round meaning in Chinese

循环扫描

Regarding the hysteretic properties and time - varying of the system , the scan round performance of the controller , adopt incremental pid algorithm in constant - pressure controlling and combine it with the integral - separated dead - zone algorithm as appropriate for the situation of the measuring system and applies fuzzy self - tuning to control pid controller parameters
由于系统的滞后时变性和控制器的循环扫描工作方式,恒压控制采用增量式pid控制算法,结合测量系统实际情况加入积分分离带死区改进算法,并对pid参数进行模糊自整定控制,设计了一种参数自整定模糊pid控制器。
