Hi guys,
I have a brushed DC motor vacuum pump that needs to hit a target vacuum and maintain that level with a constant minimal leak. Meaning the vacuum will never be stable. I have 2 options for motor control
1. PID system which keeps the motor running constantly
2. An algorithm that runs the motor to achieve a vacuum +15% above target, stops the motor and comes on again after the vacuum reaches -15% below target vacuum and repeats the process indefinitely.
Which one will lead to longer motor life?
