delay cascade 中文意思是什麼
delay cascade
解釋
滯后級聯-
The use of time delays on these vehicles helps to eliminate transmission and motor damage by providing even and controlled acceleration. the delay is adjustable between 0 to 5 seconds and can be wired independently of other delays or alternatively these delays can be wired in cascade so that it is necessary for the first delay to switch on before the following commences timing etc. suppression is included in the delay circuit to prevent damage by voltage transients
延遲開關可以調整延遲時間0 ~ 5秒，並可連接數個延遲開關來逐步控制連續動作之時間（復數連接時，第一個開關要啟動接下來的開關才會跟著動作）避免電動車起動初期之電力脈沖，達到平順的起步動作，可預防電壓無端變動造成之電路故障 -
Dynamic matrix control ( dmc ) can directly treat with objects with pure delay, has strong adaptability to large inertia, approved tracking performance and better robustness, but primary steam temperature object and boiler fuel regulating object are both intricate objects with large inertia and time delay, which are difficult to obtain perfect control effect using routine pid cascade control
由於動態矩陣控制（ dmc ）能直接處理帶有純滯后的對象，對大慣性有很強的適應能力，有良好的跟蹤性能和較強的魯棒性，而主汽溫對象和鍋爐燃料調節對象均是具有大慣性大延遲的復雜對象，用常規pid串級控制難以取得理想的控制效果。 -
To import the smith predictor into cascade control can improve the weaken control quality caused by the large time - delay in it, and reduce the predictor ' s sensibility to object parameters
另一方面，由於smith預估補償控制系統對補償控制器與被控對象的數學模型之間的誤差十分敏感，補償誤差的細微變化都將引起控製品質的很大改變。 -
This paper deeply discusses the cascade control system and the smith - predictor system of the conventional control system, states a combination system between them in order to improve the weaken control quality of the cascade system which involve a negligible large time - delay in its inner loop
本文對常規控制理論中的串級控制和smith預估補償控制兩種控制方案進行了討論，引出了利用smith預估補償控制特點來解決串級控制系統的副迴路中存在大純滯后環節時，系統控製品質差的問題。
