PID Controller Simulator

Real-time Simulation

Proportional-Integral-Derivative (PID) control is the most widespread control algorithm. Tune the P, I, and D parameters below to see how the Controller Output (CO) automatically adjusts to bring the Process Variable (PV) to the Setpoint (SP) after a step disturbance.

Tuning
Parameters

Proportional Gain (Kp) 2.0
Increases speed, but too high causes oscillation.
Integral Time (Ti) 5.0 s
Eliminates steady-state error. Smaller value = stronger integral action.
Derivative Time (Td) 0.5 s
Dampens oscillations by anticipating future error.
