  • 1. nfi PID Controllers Dedicated Control System www.nfiautomation.org
  • 2. PID ControlFeedback 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 www.nfiautomation.org
  • 3. PID ControlFeedback 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. www.nfiautomation.org
  • 4. PID ControlSpecification of PID  Relay Type Output – DTC 1000R – [ Contact ]  Current type Output – DTC 1000C [ 4~20 mA ]  Voltage Type Output – DTC 1000V [ 0 ~ 10 VDC ] www.nfiautomation.org
