科爾摩根 R43HENA-R2-NS-VS-00 伺服電機(jī)
生產(chǎn)工藝在過去進(jìn)入工業(yè)時代以后，已經(jīng)逐步成熟起來了，到現(xiàn)在我們?nèi)ジ淖円粋€工藝是很難的，因為能改變的我們基本都改變了，就是說工藝上對控制系統(tǒng)的處理速度很難有大的變化。對于用戶最關(guān)心的工藝流程的效率或者精細(xì)度提升而言，其實從兩方面可以去優(yōu)化它，一個是它的整個的生產(chǎn)流程管理、整個的物料這方面的精細(xì)化管理。另一個就是對設(shè)備的精細(xì)化管理。
但是在這一塊來看，其實我們設(shè)備在過去20年上一代高端控制器的能力控制下，它的處理速度是沒有任何問題的，可以完全滿足工藝需求的，更快的控制系統(tǒng)對于改善和提升工廠的運(yùn)營收益已經(jīng)很難體現(xiàn)價值了。就像在高速公路上跑，你跑到500邁沒有意義，因為對于穩(wěn)定可靠性來說，我們制造一個車能跑到200多邁就達(dá)到期望了，就夠用了，你再快的速度也用不上，反而帶來潛在危害。在這種情況下，我們一味的再去像過去的時候，去追求比一個高端處理器多快，這個已經(jīng)沒有意義了。但有一點跟以前一樣，它的穩(wěn)定可靠性，就像我為什么要開轎車，不去騎摩托車呢？它畢竟安全可靠性要好。
高端控制器現(xiàn)在來看，不是說看能帶多少點，處理速度快到什么程度，因為這些發(fā)展到上一代的時候已經(jīng)不是事了，現(xiàn)在隨便拿一個中小型控制器，說帶點能力和處理速度達(dá)到大型控制器的水平也都沒太大差距。但是核心的東西就是它的安全性、穩(wěn)定可靠性，它的系統(tǒng)的通訊能力，因為過去大型PLC主要是做大系統(tǒng)，大系統(tǒng)一定是有相互之間通訊，有協(xié)同的管理能力，與上位機(jī)通訊的能力、支持能力，這些能力都是判斷這個系統(tǒng)是高端控制系統(tǒng)，還是中小型控制系統(tǒng)。
The following subsections will explore illustrative examples to make both the problem and the solution(s) b.
A common area of confusion among students first approaching this topic is deciding where to place the dynamic compensation function in a feedforward control system. The answer to this question is surprisingly simple, although it may seem elusive at first glance. The key is found in the following principle: the only time-dynamic we have the ability to alter with our control system is the dynamic of the final control element. We cannot alter the time-dynamic of the load’s effect on the process variable, as that is strictly a function of process physics.
Therefore, when we test a process employing feedforward control with an eye toward incorporating dynamic compensation, we must measure the time lag of the load’s effect on PV and also the time lag of our final control element’s effect on PV, then compare those two time lags. If the final control element’s time lag is shorter (quicker) than the load’s, then we must add a delay or lag to the feedforward signal so that the final control element’s preemptive b does not occur too soon. If the final control element’s time lag is longer (slower) than the load’s, then we must either find a way to alter the process itself to decrease the load’s time lag, or add a “l(fā)ead” function to the feedforward signal in order to advance the final control element’s response and thereby ensure the preemptive b does not occur too late. Remember, all we can do with dynamic compensation is alter how the final control element responds (i.e. how slowly or quickly the preemptive b of feedforward occurs). The load’s effect on the process variable is fixed by the physics of the process and therefore lies beyond our direct control.
