Novel Tuning Strategy for Two-Degree-of-Freedom PI Controllers
نویسندگان
چکیده
In this paper, a new tuning procedure for PI controllers in Two-Degree-of-Freedom (2DOF) structure is proposed. In design procedure, First Order plus Dead Time (FOPDT) model is used. The aim is to have good set point tracking and disturbance rejection and also maximum robustness to model uncertainties. The tuning strategy is based on using analytical rules and some conceptual rules about closed loop poles and also an exhaustive search. Simulation results demonstrate the effectiveness and validity of proposed method in coping with conflicting design objectives for a wide variety of processes including minimum phase and non-minimum phase and also integrating processes.

Analytical Robust Tuning Approach for Two-Degree-of-Freedom PI/PID Controllers
This paper’s aim is to present a tuning approach for full Two-Degree-of-Freedom (2-DoF) PI and PID controllers for First-Order-Plus-Dead-Time (FOPDT) and Second-OrderPlus-Dead-Time (SOPDT) controlled processes. The tuning relations provide the value of the typical parameters for a PID controller plus the set-point weighting factor, being these relations driven by just one single design paramete...

The article describes the unified approach to the tuning of the analog and digital PI controller with two-degree-of-freedom by the multiple dominant pole method for integrating plants with a time delay on the basis of D-transform. The approach is fully analytical and it enables so tuning that the servo and regulatory responses are non-oscillatory without overshoots. The uses are shown in the ex...

The aim of the paper is to present tuning equations for one-degree-of-freedom (1DoF) proportional integral (PI) and proportional integral derivative (PID) controllers. These are based on a performance/robustness trade-off analysis with firstand second-order plus deadtime models. On the basis of this analysis a tuning method is developed for 1DoF PI and PID controllers for servo and regulatory c...
متن کاملMs Based Approach for Simple Robust PI Controller Tuning Design
This paper addresses the problem of providing simple tuning rules for a Two-Degree-of-Freedom (2-DoF) PI controller (PI2) with robustness considerations. In order to deal with the well known performance/robustness tradeoff, an analysis is conducted first that allows the determination of the lowest closed-loop time constant that guarantees a desired robustness. Simple tuning rules are generated ...
