摘要: 采用工程设计方法确定PI调节器参数后,系统性能指标不尽理想时,则应采用PID调节器对系统进行校正,可将Ziegler-Nichols方法拓展为直接利用PID与PI调节器的关系比例系数来确定PID调节器的参数,经仿真结果证明能收到较好的控制效果.关键词:整定 调节器 系统 仿真 ...
The parameter estimates serve for computing of the ultimate (critical) proportional gain and period of oscillations on the basis of modified Ziegler-Nichols method for digital control loops. The relations for setting procedures in case of the 2nd and the 3rd order model are derived in the form ...
I read from some source, using the Zeigler Nichols method, the gains are obtained from a combination of dead time and time constant instead of ultimate gain/period. I wonder if the “ultimate gain/period” also works for a system with time delay? Thank you! Jacques: March 18, 2017 at 1...

This seems to be what theControl Engineeringarticle praises as the ultimate in technology. While we can consider the Ziegler-Nichols rule helpful, there are more robust alternatives available today. You can test the method using yourDAP system. Download thefree commandcode and find out for ...
The Ziegler-Nichols tuning rules (bottom) can be used to compute modestly aggressive values for the tuning parameters according to the values of the process’s ultimate period Tu and ultimate gain Pu. Commercial Auto Tuners Variations on the relay method have become a de facto standard for ...

The Ziegler-Nicholsfrequency response (ZNfr) method is examined using the Nyquist stability criterion to implement the automatictuning of PI controller by determining the ultimate gain, Ku, and ultimate period, Tu, of a process model, whichconsists of components from adaptive optics (AO) system. ...
Ziegler-Nichols TuningModel Based TuningAutomatic control loop tuning using the relay oscillation tuning method has been used to identify the process parameters of ultimate gain and ultimate period. Ziegler-Nichols or modified Ziegler-Nichols tuning rules may be used to determine PID loop settings. ...
