Simple PID tuning Generator (BETA)

A simple Ziegler-Nichols PID tuning generator that helps you find optimal P, PI, PD, or PID controller values based on the closed-loop oscillation method. Enter your system's ultimate gain and period to get recommended tuning parameters quickly and easily.

How to use the Ziegler-Nichols method to tune your PID controller

In your controller, start by setting I (integral gain) and D (derivative gain) to zero.
Then, slowly increase P (proportional gain) until the system reaches a stable oscillation.
This P value is your ultimate gain, K_u.
Next, measure the period of the oscillation, T_u. Finally, use the Ziegler-Nichols method to find the optimal P/PI/PD/PID tuning parameters.
