Det är nog Ziegler–Nichols självsvängningsmetod du har stött på. Den är absolut en bra metod för at ställa in en PID-regulator utan en massa
Keywords: PID, controllerdesign, Ziegler-Nicholsmethod, time delay, rational approximation 1 Introduction Ever since the days of the emergence of the Ziegler-Nichols famous methods ([1]) for choice of parameters in a PI or PID controller for a certain process model, there has been attempts to find improved methods for tuning the PID param-eters.
Moreover, simulation results of self-tuning PID controller using Ziegler-Nichols are acquired from programmable logic controller (PLC), and then are given in related topics. PID is an acronym for Proportional Integral Derivative, which also happens to be the three main mathematical elements (terms) of the PID controller. Depending on your system you might want to mix-and-match these terms. Some systems may only require a P, PI or a PD controller while others require the full PID package. Un código un poco duro de entender bien para mí. No sabía que existiera un método empírico para calcular un PID. Probablemente es una cosa muy tonta pero no sé si habrás tenido en cuenta que los parámetros que se obtienen con Ziegler-Nichols no se corresponden con Kp, Ki y Kd que se introducen en un PID. Ziegler-Nichols-methode. In de jaren 40 hebben John G. Ziegler en Nathaniel B. Nichols proefsgewijs afstelregels voor het correct instellen van een P-, PI- of PID-regelaar ontwikkeld, zodat deze op acceptabele wijze op verstoringen kan reageren zonder dat er instabiliteit in het systeem ontstaat.

The goal of Ziegler-Nichols PID tuning is to achieve good disturbance rejection. In the MATLAB Code attached, the plant transfer function, G (s) is first generated from the inputs entered by the user (numerator and denominator of the transfer function). The plant transfer function is used to obtain the closed loop margins (Ku and Tu).

2020-08-24 · This process is known as “tuning” the PID controller. Ziegler-Nichols. The Ziegler-Nichols tuning method is one of the most famous ways to experimentally tune a PID controller. The basic algorithm is as follows: Turn off the Integral and Derivative components for the controller; only use Proportional control. According to Ziegler Nicholas table: Table 2 Ziegler Nicholas Tuning Chart Controller Type Kp Ti (sec) Td (sec) P 0.5*Kc = 0.5*8=4 100000 0 PI 0.45*Kc = 0.45*8=3.6 0.83*Pu=0.83*36.32=30.1 0 PID 0.59* Kc = 0.59*8=4.7 0.5*Pu=0.5*36.32=18.2 0.12*Pu =0.12*36.32=4.4 A popular method for tuning P, PI, and PID controllers is the Ziegler–Nichols method.
