Analytical Design of PI Controller for First Order Transfer Function plus Time Delay: Stability Triangle Approach

A Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes

This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...

Comparative Analysis of Stability and Robustness between Integer and Fractional-Order PI Controllers for First Order Plus Time Delay Plants

This work carries out a comparative analysis of the stability robustness of PI and PI controllers when applied to first order plus time delay plants. An analytical result shows that both controllers have exactly the same region of feasible frequency specifications. Nevertheless, the robustness of both controllers is quite different. Depending on the set of frequency specifications and the non i...

Remote-Tuning – Case Study of PI Controller for the First-Order-Plus-Dead-Time Systems

Robust PI/PID controller for interval first order system with time delay

In this paper, a new approach to determine the entire set of stabilisng PI/PID parameters for time delay process with bounded uncertainties has been developed. Our method exploited a combination of the generalised Kharitonov theorem and the Hermit Biehler theorem extended for quasipolynomials to synthesise a robustly stabilising controller. By using a constructive procedure, we obtain all PI an...
