1.3.2.1. Poorly Tuned Control Loop
A poorly tuned control loop may respond to an error change too quickly and overshoot the setpoint
value, respond to slowly and never return to setpoint value or continually oscillate above and below the
setpoint value (See Figure 2). For an output that responds too quickly and continues to overshoot,
Paragon Controls suggests increasing the 1/D and Reset values in small increments to slow the response.
An output that gradually approaches the setpoint but never really gets there is too slow. Paragon
Controls suggests decreasing the 1/D and Reset values in small increments to speed up the response.
