Ziegler-Nichols tuning rules have been widely used in process control where the plant dynamics are unknown. When the plant model is available, other controller design methods exists. Generally, to apply the step response method, one needs to obtain the S-shape response. Plants with complicated dynamics but no integrators are usually the cases.

Ziegler -Nichols (ZN) Controller is also included with which we can see Table 1 - Ziegler-Nichols table for the closed-loop method The automatic adjust of Out Bias_ brings us to the situation were the upper and lower actuation values of the relay produce similar effect on the process, resulting in a better approximation of the mathematical model Table of Contents. Ziegler-Nichols Loop Tuning. The Ziegler-Nichols loop tuning protocol 1) is a simple method to establishing the loop parameter values for a PI or PID control loop. This protocol is designed to optimize the loop for disturbance rejection.

Such determination of the parameters of PID controllers or tuning of PID controllers can be made by engineers on site by experiments on the plant. The Ziegler-Nichols tuning rules are generally regarded as too aggressive for most process control applications. In 1992, based on collaborative research between the Dow Chemical Company and Lehigh University, Bjorn Tyreus and William Luyben proposed the … Ziegler-Nichols Tuning Rule.
