New tuning rules for PI and fractional PI controllers
نویسنده
چکیده
This paper presents new tuning rules for PI and fractional PI control of processes that are typically found in process control. The rules are based on characterization of process dynamics by three parameters that can be obtained from a simple step response experiment. The rules are obtained by minimizing a frequency objective function subject to a constraint on the maximum sensitivity. Comparisons with classical tuning rules show that they are very simple but give substantially better performance.

Practical Tuning Rule Development for Fractional Order Proportional and Integral Controllers
This paper presents a new practical tuning method for fractional order proportional and integral (FO-PI) controller. The plant to be controlled is mainly first order plus delay time (FOPDT). The tuning is optimum in the sense that the load disturbance rejection is optimized yet with a constraint on the maximum or peak sensitivity. We generalized Ms constrained integral (MIGO) based controller t...
متن کاملOn Fractional PI Controllers: Some Tuning Rules for Robustness to Plant Uncertainties
The objective of this work is to find out optimum settings for a fractional PI controller in order to fulfil three different robustness specifications of design for the compensated system, taking advantage of the fractional order, λ. Since this fractional controller has one parameter more than the conventional PI controller, one more specification can be fulfilled, improving the performance of ...
متن کاملFractional Order PI Tuning for Integrating Plants with Time Delay ⋆
In the last decade, non-integer order controllers have received great attention, due to their capacity of achieving robustness of the controlled loops with respect to gain and parameter variations of the plant. However, despite the general interest, technical literature offers few widely accepted and easy tuning techniques for these new controllers. To overcome the lack of simple tuning rules, ...

This paper aims to apply the practical tuning procedure for fractional order proportional and integral controller (FO-PI) to two experimental platforms. The first platform is Quanser’s Heat Flow Experiment (HFE) and the second platform is the Quanser’s Rotary Flexible Joint (RFJ) Module. The fractional controllers in both cases have been digitally implemented using Oustaloup’s recursive approxi...
