本文提出了两套分数 PID 整定规则。这些规则是二次的，并且需要与（通常，整数）PID 的第一个 Ziegler-Nichols 调整规则所使用的相同的工厂时间响应数据。因此，不需要控制对象的模型，只需要 S 形阶跃响应。即使模型已知，规则也可以快速提供微调的起点。结果与使用规则调整的整数 PID 获得的结果相比较。
In this paper two sets of tuning rules for fractional PIDs are presented. These rules are quadratic and require the same plant time–response data used by the first Ziegler–Nichols tuning rule for (usual, integer) PIDs. Hence no model for the plant to control is needed—only an S-shaped step response is. Even if a model is known rules quickly provide a starting point for fine tuning. Results compare well with those obtained with rule-tuned integer PIDs.
