② PID運算電路 根據(jù)整定好的參數(shù)用以對偏差信號進(jìn)行比例、徽分和積分的運算，是調(diào)節(jié)器實現(xiàn)PID控制規(guī)律的關(guān)鍵環(huán)節(jié)。它與物人電路及放大器的信號問題將在后面的基型調(diào)節(jié)器中詳細(xì)討論。
③輸出電路 將運算電路的輸出信號做zui后一次放大，或者作為運算電路主回路中放大器的zui后一級，提供調(diào)節(jié)器的輸出信號。
④手動操作電路 由于系統(tǒng)上或工藝上的需要，有時要進(jìn)行人工控制。因此，在有的調(diào)節(jié)器中備有手動操作電路，它能輸出一個由操作人員控制的 “手動電流’到執(zhí)行器去，即人工控制。“手動”與“自動”可以借助手動- 自動切換開關(guān)進(jìn)行切換。
⑤輸出限幅電路 在有的調(diào)節(jié)器中，設(shè)有輸出限幅電路，用以將調(diào)節(jié)器的輸出限制在一定范圍內(nèi)，從而保證調(diào)節(jié)悶不處于危險開度。調(diào)節(jié)器愉出的上限值和下限值都可以調(diào)節(jié)。
