In this thesis , a load feedback low - frequency fatigue - testing machine controlled by microprocessor is developed . the machine adopts advanced electro - hydraulic servo system , which is controlled by micro - computer ( mcs - 51 single chip processor ) 本文讨论了微机控制的负载反馈式疲劳试验机的研制,该试验机所采用的是先进的mcs ? 51系列单片机控制电液伺服系统。
The s7 - 200 plc has the digital controlling signals and the analog controlling signals . the s7 - 200 plc is easy to be used for machine controlling . the software are written in lad or the language stl and controlled by the developing software step7 - micro / win 软件部分有上位机和下位机软件两种,上位机直接用plc配置的应用开发软件,下位机是用s7 - 200提供的编程语言编写程序。
The four departments generation set of 360 mw power plant from french alstom by huaneng luohuang power plant , its steam machine control system , including steam machine regulation and steam machine protection system are designed by french gec - alstom dem company 华能珞璜电厂四台360mw燃煤发电机组系由法国alstom全套引进,其汽机控制系统,包括汽机调节、汽机保护系统均由法国gec - alstomdem公司开发设计。
Consider a machine control system that needs to control a linear stage , rotate multiple shafts , control lighting and read in video data ; in a system like this , there are multiple processes that must happen deterministically , in real - time , and in parallel 考虑到一个机器控制系统需要控制一个线性电路级,旋转多个轴,控制照明和视频数据的读取,因此,在这样一个系统中,同时有多个进程必须独立、实时、并行发生。
The paper puts forward an idea of designing for stove temperature of injection machine control system by designing the fuzzy set theory , and introduces the structure of the fuzzy controller , the design procedures of the fuzzy control regulations and realization method 摘要根据注塑机料筒温度的自动控制问题,提出了采用模糊控制理论来设计温度控制系统的思路,并介绍了模糊控制器的结构、模糊控制规则的设计及实现方法。
With its leadership in r & d and production of computerized embroidery machine control system , beijing xingdahao is pushing forward the development of the whole embroidery machine industry and has expanded its products line to the whole sewing equipment control system area 北京兴大豪科技开发有限公司是专业从事电脑刺绣机控制系统研制和生产的旗舰企业,引领并推动整个刺绣机行业的发展,并面向整个缝制设备控制系统领域延伸。
Secondly , a new method on man - machine control is proposed . the axis - aligned bounding boxes arithmetic ( aabb ) and sphere area query arithmetic is applied to realize the collision effect of the virtual people in the launch vehicle testing hall 其次,本文对人机交互控制提出了一种新的实现方法,漫游时碰撞检测则采用了轴向包围盒法( axis - alignedboundingboxes : aabb算法)和球体区域查询算法来实现虚拟人物与火箭测试大厅内物体的碰撞效果。
Like this even if once on the position machine breaks down , also does not affect the lower position machine control , causes the plc system the production control function and the information management function merges into one organic whole , the realization " the danger is dispersible , control centralism " goal 这样即使一旦上位机发生故障,也不影响下位机的控制,使得plc系统的生产控制功能和上位机的信息管理功能融为一体,实现“危险分散、控制集中”的目的。
As a high performance and new machines control strategy developed in 1980 ' s , direct torque control solves the problems that computation in vector transformation control is complex , the control characters are easily affected by the changes in machines parameters , real results of the experiments ca n ' t achieve the level of the theoretical analysis 而作为在80年代中发展起来的高性能的新型电机调速方法,直接转矩控制又在很大程度上解决了矢量控制中计算控制复杂、特性易受电动机参数变化的影响、实际性能难于达到理论分析结果的一些重大问题。
