摘要

针对(可能的)高阶过程/模型，提出了一种新的过程-反应曲线整定PID控制器的方法。该方法与Ziegler-Nichols过程反应曲线法类似，即只需从开环阶跃响应中识别最大斜率和滞后即可。相对延时误差(相对延时裕度)δ为调谐参数。通过大量的数值模拟验证了所提出的方法，并发现在许多驱动过程的例子中接近最优。为了处理广泛的过程模型集，提出了两种模型约简方法。

A Novel Process-Reaction Curve Method for Tuning PID Controllers

A novel process-reaction curve method for tuning PID controllers for (possible) higher order processes/models is presented. The proposed method is similar to the Ziegler-Nichols process reaction curve method, viz. only the maximum slope and lag need to be identified from an open loop step response. The relative time delay error (relative delay margin), δ is the tuning parameter. The proposed method is verified through extensive numerical simulations and is found close to optimal in many of the motivated process examples. In order to handle the wide set of process models, two model reduction modes are presented.

期刊介绍： The aim of MIC is to present Nordic research activities in the field of modeling, identification and control to the international scientific community. Historically, the articles published in MIC presented the results of research carried out in Norway, or sponsored primarily by a Norwegian institution. Since 2009 the journal also accepts papers from the other Nordic countries.
