Understanding Transistor Function in Control Systems

Click For Summary
SUMMARY

Transistors serve as essential components in control systems primarily functioning as amplifiers, boosting weak input signals to produce stronger outputs. Their efficiency, characterized by low heat loss and rapid response times, has led to their widespread adoption, replacing less efficient vacuum tubes. Understanding feedback mechanisms, both positive and negative, is crucial in grasping the role of transistors within circuit configurations. The discussion highlights the importance of transistors in modern electronic systems and their advantages over older technologies.

in control system, why have so many device like transistor? Wat is them function?
 
Engineering news on Phys.org
The essence of a control system is feedback to control output. It may be positive or negative as described here:
http://en.wikipedia.org/wiki/Electronic_feedback_loops#Types_of_feedback

It's not directly related to a transister but is rather a circuit configuration.


The transister is used primarily as an amplifier, that is, boosting a weak input to provide a more powerful output.
Here is one brief explanation:

Transisters are widely used in many circuits because of their efficiency...very low heat loss for example...and fast response times..they replaced vacuum tubes which used a lot more power and could not be made nearly as small as solid state transisters.
