The Ziegler-Nichols Method is one of the best known tuning methods, that is based an open loop step-response function of time (Ziegler (1942)). The produced response function is approached by a first order transfer function with dead time. Applying the extracted parameters (K, τ and Ds) heuristic tables are utilized fortuning.
The Ziegler–Nichols method is too aggressive for many industrial control systems. For example, for a proportional controller, the method specifies a GM of just 6 dB, compared with the 12 dB in the P controller tuned earlier in this chapter (Figure 6.5). Ziegler-Nichols Method: First, note whether the required proportional control gain is positive or negative. To do so, step the input u up Turn the controller to P-only mode, i.e.
La méthode présentée ici est celle utilisant la génération de l'oscillation entretenue en boucle fermée: Tout d'abord, on annule l'action intégrale et l'action dérivée. Ziegler and Nichols actually proposed two such techniques, both of which are described in “Loop Tuning Fundamentals,” Control Engineering, July 2003. Auto-tuning. For many years, Ziegler-Nichols tuning techniques were strictly manual operations executed whenever a new control loop was commissioned. Similar to the Ziegler–Nichols method, a set of tuning parameters were developed to yield a closed-loop response with a decay ratio of 1/4.
