All of these signals are gainadjusted, filtered and summed in an analog control computer . 所有這些訊號在模擬控制計算機中進行增益調(diào)整、濾波和綜合。
Speed signal with multi - step and analog control 速度信號支持多段速控制和模擬量信號控制
Analog control equipment 模擬控制設(shè)備
Analog control channel 模擬控制信道
Entertainment technology - lighting control systems - 0 to 10v analog control specification 娛樂技術(shù).照明控制系統(tǒng). 0至10v模擬控制規(guī)范
There are two kinds of control system of analog control and digital control 這樣的控制系統(tǒng)基本上可分為2種類型:模擬控制和數(shù)字控制。
Flexible dimming control utilizes either an analog control signal or direct digital pwm control without external rc filtering . this also increases dimming accuracy at low brightness levels 電路采用靈活的調(diào)光控制方式,既可輸入模擬控制信號,也可直接輸入數(shù)字脈沖寬度調(diào)制信號而不需要外置rc濾波器。
The control circuit built with conventional analog control is unavoidably cumbersome , the digital control method can simplify the design of circuit , and can satisfy the requirement of the lamps well 傳統(tǒng)的模擬控制往往顯得麻煩且復(fù)雜,數(shù)字控制能夠簡化電路設(shè)計,并且可以使其更好地滿足燈負載的要求。
Digital control is being paid more and more attention in power electronics for its advantages such as control flexibility , performance stability and more powerful functions , compared with conventional analog control 數(shù)字化控制以控制簡單、靈活,輸出性能更加穩(wěn)定,可以實現(xiàn)模擬控制所不可達到的功能等諸多優(yōu)勢成為電源研究領(lǐng)域的一大熱點。
Great progress of microprocessor and peripheral circuit causes distinct improvements in digital control techniques . then , digital control technique will gradually substitute analog control technique for controlling power electronic system 微處理器及其外圍電路的發(fā)展,使得數(shù)字控制技術(shù)所存在的一些問題不斷得到改善,并逐漸取代模擬控制技術(shù)實現(xiàn)系統(tǒng)的控制功能。
