Feedback control requires being able to sense the variable being controlled.
Because electrical signals can be transmitted, amplified, and processed easily, often we want to have a sensor whose output is a voltage or current proportional to the variable being measured. Describe a sensor that would give an electrical output proportional to :
(A) Temperature (온도)
(B) Pressure (압력)
(C) Liquid level (액체 상태)
(D) Flow of liquid along a pipe (or blood along an artery) force
(E) Linear position
(F) Rotational position
(G) Linear velocity
(H) Rotational speed
(I) Translational acceleration
(J) Torque (토크)
위 문제 입니다. 무슨 말인지??
컨트롤 시스템의 전류 전압이 아래 상황에 따라서 왜 변하는가 물어 보는건가요?
