专用模块 meaning in English
personal module
Examples
- In the system framework , the technique of expert system as a special module could promote the intelligence of this system
在系统框架中，以专用模块的形式采用设计评价专家系统技术，可以提高设计评价的智能化程度。 - Disadvantages of the approach are the large number of dedicated modules and their limited adaptability for an algorithm to be modified . adaptation to a new coding scheme can result in a redesign
其缺点在于其中有大量的专用模块，当算法需要修改时，便无法适应新的算法，只能重新设计。 - The fcs system consists of one upper pc and several fieldbus modules . the upper pc can be realized with a traditional pc or the special record module designed in the dissertation , which can record , input and display
该系统由上位机和现场总线模块构成,上位机可由传统的pc机实现或由本文开发具有记录,键盘输入及显示功能的专用模块实现。 - Cad and cam have had a rapid development from 1950 ' s . some special systems for structure design had been developed , as well as some software libraries and blocks for bridge structure design based on autocad
随着cad / cam技术的飞速发展，各类专用设计的软件应运而尘，如在结构设计领域开发了专用的设计系统；在桥梁结构设计领域开发了基于autocad的桥梁结构的部分软件库和若干专用模块等等。 - Motion control is a comprehensive subject . modern ac drive is a important embranchment in the field of motion control . however , it is difficult to rea1ize high - performance ac drive systems because induction motors are a kind of strongly - coupled nonlinear system with many variables and the torque is not easy to control . with vector control technology decoupling and torque control of ac motor are solved . the basic idea of vector control is that three - phase system is equiva1ent to two - phase system by coordinate transformation and it realizes the decoupling between field current and torque current of the stator in order to control the flux and current respectively , thus induction motor can be considered dc motor and high performance is achieved easily . with the progress of electric and electronic technology and the development of computer , high - integrated special modules and high - precision digital signal processor ( dsp ) are applied to ac drive so that vector control has been developed rapidly
但是高性能的交流调速系统实现很困难，这是因为交流电机是多变量、强耦合的非线性系统，不易实现高性能转矩控制。矢量控制技术则解决了交流电机解耦与转矩控制问题，其基本思路? ?应用坐标变换将三相等效为二相，实现定子励磁电流分量与转矩电流分量之间的解耦，达到对交流电机磁链与电流分别控制的目的，交流电机等效为直流电机实现高性能调速。随着电力电子技术的进步，计算机技术飞跃发展，高度集成的专用模块和高精度的数字信号处理器应用于交流传动系统中，促进矢量控制迅猛发展，日趋成熟。
