The Ziegler-Nichols tuning method is a heuristic method of tuning a PID controller.It was developed by John G. Ziegler and Nathaniel B. Nichols.It is performed by setting the I (integral) and D (derivative) gains to zero. The P (proportional) gain, is then increased (from zero) until it reaches the ultimate gain, at which the output of the control loop has stable and consistent oscillations Ziegler og Nichols anbefaler å redusere P-bidraget med 10 %; slik: Med de samme observasjonsdata, kalkulerer vi P-verdien til å bli: P = (0,9 / (3 sekunder * 2,5 reaksjonsrate) = 0,12 Og, dersom denne skal oppgi i forsterkningsprosenter blir tallet 0,12 * 100 = 12 [prosent]
The time-honored Ziegler-Nichols tuning rule [2,3] (Z-N rule), as introduced in the 1940s, had a large impact in making PID feedback controls acceptable to control engineers.PID was known, but applied only reluctantly because of stability concerns. With the Ziegler-Nichols rule, engineers finally had a practical and systematic way of tuning PID loops for improved performance Baserer ikke Ziegler og Nichols 2. metode seg på at sløyfen er åpen, mens i 1. metode så er sløyfen lukket?

In this short tutorial I will take you through the two Ziegler-Nichols tuning methods. This will let you tune the derivative, proportional and integral gains.. Noen lærebokforfattere gjør noen forutsetninger som avviker fra Ziegler og Nichols ved at de forutsetter at deres prosess er selv-regulerende. Imidlertid, dette gjør ikke Ziegler og Nichols. Deres metodebeskrivelse kan brukes på både selv-regulerende og ikke-selv-regulerende prosesser! Slik så det ut i 1941 på Metode 2
Ziegler-Nichols PID-tuningmetode er uegnet i prosessregulering, men vi presenterer aktuelle løsninger. Altfor mange reguleringssløyfer står enten i manuell, eller er helt ute av tuning slik at de ikke reagerer som forventet på hendelser i sine omgivelser Ziegler and Nichols determined the adjustments based on a specific plant model. The steps for tuning a PID controller via the 2nd method is as follows: Using only proportional feedback control: 1. Reduce the integrator and derivative gains to 0. 2. Increase Kp from 0 to some critical value Kp=Kcr at which sustained oscillations occur. If it doe Ziegler-Nichols used a specific single-stage pneumatic controller to come up with these rules. Their controller was a series one, but also had the further complication of (1 - D/I) factor in their effective Proportional Band. Consequently, their PID settings are more conservative in D.

Ziegler and Nichols were careful to qualify quarter-wave damping as less than optimal for some applications. In their own words The statement that a sensitivity setting of one half the ultimate with attendant 25 per cent amplitude ratio gives optimum control must be modified in some cases Ziegler-Nichols Method: First, note whether the required proportional control gain is positive or negative. To do so, step the input u up (increased) a little, under manual control, to see if the resulting steady state value of the process output has also moved up (increased)
The Ziegler-Nichols open-loop tuning rules use three process characteristics: process gain, dead time, and time constant. These are determined by doing a step test and analyzing the results.

2. Relaxed Ziegler-Nichols PI. tuning. 2.1. Derivation of the tuning formulas. The following PI controller function is assumed: u (t) = u man + K c e (t) + K c 22.1 Ziegler and Nichols derived two empirical methods for obtaining PID controller parameters. These methods are closed-loop tuning method and open-loop tuning method.[7] The closed-loop tuning method allows the use of the ultimate gain value Ku, and the ultimate period of oscillation Pu, to calculate the PID parameters as shown in Table 4 Ziegler-Nichols Rule: Ki = 1.2 / t u; For level control (integrating processes) use: Ki = 0.6 / t u . Rules for a PID Controller. The PID tuning rule was designed for a controller with the Interactive algorithm. The tuning settings should be converted for use on controllers with Noninteractive and Parallel algorithms

With just a few modifications to the original Ziegler-Nichols tuning approach, these rules can be used to tune level control loops for both stability and fast response to setpoint changes and disturbances. Lee Payne is CEO of Dataforth 2. Literature Review John Ziegler and Nathaniel Nichols developed the Ziegler-Nichols open- loop tuning method in 1942, and it remains a popular technique for tuning controllers that use proportional, integral, and derivative actions in the industrial sector. Control system performance, in close-loop format is often measured by applying a ste Ziegler-Nichols PID tuning. Tutorial. A while back I completed tuning of my HLT using the Ziegler-Nichols method.
