11. PID control ■
◆PID adjustment methods
Use PID control when target value is fixed, observe feedback wave and proceed adjustment.
1. Increase P value to within a range that does not vibrate.
2. Reduce I value to within a range that does not vibrate.
3. Increase D value to within a range that does not vibrate.
