The system controller is synthesized by the ideal formulation of the state , output , control variables on the basic motion and the pid regulator 由準(zhǔn)穩(wěn)態(tài)運(yùn)動(dòng)的期望狀態(tài)、輸出、控制和調(diào)節(jié)器組成系統(tǒng)控制器。
When forestage dcs system or pid regulator happened fault , manipulator receiving failure signal immediately switch into manual control state , by keystroke controls operation signal output 可分別帶有一路pid控制輸出及一路變送輸出。具有多種曲線(xiàn)控制輸出功能:可實(shí)現(xiàn)曲線(xiàn)控制暫停清零步進(jìn)等。
Intelligent self - tuning pid regulator adopts advanced microprocessors for smart control , it is suitable for system required the high accuracy regulation and control , and it can automatically figure out the optimal regulating parameters according to different controlled object 適用于需要進(jìn)行高精度調(diào)節(jié)控制的系統(tǒng),并可根據(jù)被控對(duì)象自動(dòng)演算出最佳調(diào)節(jié)參數(shù)。
Intelligent manipulator is matching product of pid regulator or dcs and other system , which mainly use to manual regulation under the system running or special condition and to carry out operate as a backup instrument when main machine has happened failure or maintenance 智能自整定pid調(diào)節(jié)儀采用先進(jìn)的微處理器進(jìn)行智能控制,適用于需要進(jìn)行高精度調(diào)節(jié)控制的系統(tǒng),并可根據(jù)被控對(duì)象自動(dòng)演算出最佳調(diào)節(jié)參數(shù)。
Simple backup manipulator receive given analog quantity signal from dcs system or pid regulator , when normal control , manipulator input and output equivalen to straight - through , so as to realize that dcs system or pid regulator automatic control the actuator 且各輸入端口均具備萬(wàn)能信號(hào)輸入功能,只需通過(guò)儀表菜單的簡(jiǎn)單選定,即可實(shí)現(xiàn)不同類(lèi)型輸入信號(hào)各種熱電偶熱電阻標(biāo)準(zhǔn)信號(hào)之間的輕松切換,提高了儀表的通用性和可靠性。
In order to improve producer ' s efficiency , the mechanism such as rolling mill and shearing machine , which requests position control can go to the position in the best times and in the best mode , now , in the industrial application , open - loop control system is more used , even though in the closed - loop control system only adopts pid regulator , so time and efficiency can not reach the best 目前在工業(yè)應(yīng)用中,大多數(shù)采用的是普通的開(kāi)環(huán)控制,閉環(huán)控制中應(yīng)用的也僅僅采用了pid ,因此在時(shí)間和效率上都沒(méi)有達(dá)到最優(yōu)。本文根據(jù)這種現(xiàn)狀,對(duì)apc控制系統(tǒng)進(jìn)行開(kāi)發(fā)和應(yīng)用。目前,在工業(yè)控制中, pid調(diào)節(jié)和模糊控制應(yīng)用的比較多,也比較成熟,但在位置控制系統(tǒng)中,都沒(méi)有充分的發(fā)揮出這兩種控制方法的特點(diǎn)。
This paper make a study of controller on permanent magnetsyn - chronous motor . the permanent magnetsyn - chronous motor has many virtue such as simply structure and simle solidity etc . with this excellence . it has more and more uses in industry and agriculture . the idea of this paper is to control permanent magnetsyn - chronous motor system through vector control . to solve the problem of pid regulator , we use the fuzzy control and self adaptive pid 本文設(shè)計(jì)的思路是采用轉(zhuǎn)子磁通定向的矢量控制技術(shù),主電路采用spwm和交-直-交電壓型逆變器,其中spwm采用sa4828芯片直接產(chǎn)生,在控制器的實(shí)現(xiàn)方面,采用了tms320lf2407型dsp芯片作為主控板cpu ,實(shí)現(xiàn)了電流、轉(zhuǎn)速雙閉環(huán)的控制系統(tǒng)。
