The simulation results show that the controller is available in improving the control effect , and it can save energy than traditional tower fan sequencing control strategy 结果表明该上位机控制器具有较好的控制稳定性,并且比常规的风扇转速及台数控制方式更节能。
It is concluded that there is a very closed relationship between sedimentary sequence and gas pool . sequence controlled the association of source beds , reservoirs and cap beds , controlled the distribution 总结出沉积层序与天然气藏有着十分密切的关系;层序控制了生储盖组合,决定着储层的展布并影响储层的储集性能。
It is considered that there is a very closed relationship between sedimentary sequence and oil gas accumulation . sequence controlled the association of source beds , reservoirs and cap rocks , controlled the distribution of reservoirs and affected the stockpile function of reservoirs 认为沉积层序与油气藏有十分密切的关系:层序控制了生储盖组合,决定着储层的展布并影响储层的储集性能。
The function of the controlling system comprise time sequence control of rotating field , data collection and serial communication etc . it avails the automation of finishing process and the interface to other system by using micro - controller 本文采用单片机来实现脉冲控制的旋转磁场,实现的功能有旋转磁场的时序控制、数据采集和通信等。采用单片机有利于加工过程的自动控制和与其它系统的接口。
After 150 % capacity increasing of 30 kt pet plant , through analysis of the factors that have effect on the prepolycondensation vaccum system , effective combination the sfc sequence control with the traditional pid control , the unstable problems exist in the technology control process were solved 摘要3万t聚酯装置在扩容150 %后,通过对预缩真空系统的影响因素的分析,采取sfc顺序控制与传统pid控制有效结合,解决了工艺控制过程中存在的不稳问题。
