Observe the Effect of Proportional Gain Kp, Integral Gain Ki and Derivative Gain Kd values with respect to PID Controller Output response shown in below animation.
The below graph shown is PID Controller output response on a change in error signal. Consider the error signal is same and observe the controller output response with change in different PID controller gains.
Dotted Line – Setpoint
Blue Colour Line – PID Controller Output
Kp, Ki, Kd are PID Controller Gains
