This document discusses PID (proportional-integral-derivative) control and feedback control systems. It describes how feedback loops work using a microphone and speaker system as an example. It then discusses different types of PID controllers including those with relay, current, and voltage outputs. The document outlines various control modes like on-off control, manual control, basic PID control, and ramp/soak control. It also mentions PID alarms. The goal is to control systems using feedback to achieve the desired output.

Feedback Control – Why Should You Care?
• Microphone a Amplifier a Speaker a Microphone
• This loop happens so fast that it generates its own frequency
• Microphone-to-speaker distance dictates the frequency
– Decides how quickly sound “feedback” occurs through
the system
• This feedback problem happens in public address systems

Feedback Control – Why Should You Care?
 Attach a set of speakers to your computer
 “Un-mute” and set microphone and speakers to maximum volume
 Tap microphone and hear it in the speakers
 Place speakers near microphone, turn up the volume and hear
feedback
 Change distance between microphone and speakers to see the
effect
 Caution: Not to be used as revenge on instructors, labmates, etc.
