Controls, which replace these older controls 控件,它們將替代這些較舊的控件。
All of the tests that use the old controls will now be broken 所有使用老控件的測試都將中斷。
Some examples of older controls that do not work correctly with visual studio are 在visualstudio中無法正常使用的舊控件的示例有:
Control in a simple data-bound scenario without customizations, you can simply replace the old control with the new control 控件,則可以簡單地使用新控件替換舊控件。
The delay of the system is in the range, so the older control parameter can make the system steady 由于系統(tǒng)的延遲時間落在使系統(tǒng)穩(wěn)定的范圍內(nèi),所以控制算法中采用原控制參數(shù)能夠使系統(tǒng)穩(wěn)定。
So, it needs to build the necessary support platform in hot strip mill, for example, reforming the old control system and building the production management system 為此,需在相關(guān)生產(chǎn)廠建立必要的支撐平臺,如對原有控制系統(tǒng)進(jìn)行改造、建立生產(chǎn)管理計(jì)算機(jī)系統(tǒng)等。
Because of the defect of old control system, the thesis developed a intelligence module dqlon which were made up intellect distributed control system-fieldbus control system with fieldbus standard 本文是針對傳統(tǒng)控制的系統(tǒng)的缺點(diǎn)和不足,利用現(xiàn)場總線標(biāo)準(zhǔn)開發(fā)一種智能模塊dqlon,用它組成智能型分布式控制網(wǎng)絡(luò)??局部操作網(wǎng)絡(luò)(lon),即現(xiàn)場總線系統(tǒng)。
The dissertation makes use of vhdl to design an asic of the control system of automatic notes system, uart, and circular impulse distributor . the experiment results indicated that the system is superior to the old control system in size, reliability and the capability of anti-jamming 仿真、調(diào)試經(jīng)驗(yàn)表明,該控制系統(tǒng)能夠較好完成設(shè)計(jì)所具有的控制性能,且還具有體積小、可靠性高和抗干擾能力強(qiáng)等特點(diǎn)。
By analyzing the existing problems of the old control system, this article explains it is reasonable and scientific of using ac servo control system . the whole machine has been finished the commissioning and run the protocol, the combination is running stably and accepted by the cigarette factory 在控制系統(tǒng)的技術(shù)路線以及閉環(huán)控制電路分析的基礎(chǔ)上,完成了交流伺服系統(tǒng)的總體設(shè)計(jì),并對軸編碼器以及plc控制系統(tǒng)的功能做進(jìn)一步研究。
The old control system mainly using-and-now ca n't meet the high and complicated requirements of modern ship to control its boiler . it is imperative under the situation to use computer for ship control area . and the remarkable plc used currently by industry process control area is the most reliable, simple and convention way to realize computer control on board modern ship . the paper introduce simply the basic principle of plc and the characteristic of simens plc s5-115u and a typical boiler system of huge oil tank . on this base, the paper pay more attention to making control programme of s5-115u for huge marine fuel oil boiler . and pid control method is singly adopted for water level control and steam pressure control of the fuel oil boiler 以繼電??接觸器為主的老一代控制系統(tǒng)已不能滿足現(xiàn)代船舶對其鍋爐控制的越來越高、越來越復(fù)雜的要求,這一領(lǐng)域的計(jì)算機(jī)化已勢由必行,而應(yīng)用在當(dāng)前工業(yè)過程控制領(lǐng)域中引入注目的可編程序控制器(plc)又是使其計(jì)算機(jī)化的最簡便和可靠途徑。本文主要介紹可編程序控制器(plc)的基本工作原理、德國西門子可編程序控制器s5-115u和大型油輪鍋爐的典型系統(tǒng),在此基礎(chǔ)上對用西門子s5-115u控制大型船舶燃油鍋爐進(jìn)行了編程。
