This procedure was first described in a paper published in 1942—credit to Ziegler and Nichols for coming up with a tuning method that has survived almost 75 years of overwhelming technological development. The process starts with a proportional-gain-only system. You increase the P gain until the system exhibits oscillations that are sustained (i.e., stable in terms of amplitude) and regular (i.e., stable in terms of period); the oscillation does not need to be centered Ziegler-Nichols Tuning Method •Ziegler-Nichols tuning method to determine an initial/estimated set of working PID parameters for an unknown system •Usually included with industrial process controllers and motor controllers as part of the set-up utilities –Some controllers have additional autotune routines.

Ziegler and Nichols proposed rules for determining values of proportional gain K p, integral time T i, and derivative time T d Ziegler and Nichols Kc Ti Td P Ku/2 PI Ku/2.2 Pu/1.2 PID Ku/1.7 Pu/2 Pu/8 Table 1 Ziegler Nichols parameter for PID controller On simulation we get Ku=2.9521, Pu=48.2 Therefore, by calculation using above table we get Kp=1.77, Ki=0.0735 , Kd=10.672 Fig. 3: Ziegler-Nichols SIMULINK model B. Tyreus-Luyben Method and SIMULINK model of a dc servo motor. And Ziegler-Nichols tuning method is utilized for PID control of a dc servo motor. First analyzed Ziegler-Nichols tuning gain by second method and then continued in MATLAB SIMULINK. Initial settle time of dc servo motor is around 6.34 seconds.

The original Ziegler-Nichols method moves the critical point into a point with fixed coordinates according to the chosen type of controller. For a P-controller it is the point []−0.5; −0 j, for a PI controller the point [−0.45; +0.0896 j] and for a PID controller is it []−0.6; −0.28j.
