A method of PID controller autotuning based on relay feedback control is described. Special attention is paid to the process structure and parameters estimation in the phase of reaching the desired operating point. This may increase the method's robustness and also speed up the tuning procedure. The algorithm's validity is illustrated by some simulation results and an experimental result on a laboratory pilot plant. Il est decrit la mèthode du régulateur d'autoadaptation PID basée au système asservi à relais. L'attention particulierè est consacrée à l'estimation de la structure et des paramètres du procès à la phase dans laquelle on met le proces dans le point de fonetionnement dont on augmente la robustesse et la vitesse de l'autoadaptation. Nous avons presenté certains résultats de la simulation à l'ordinateur ainsi qu'à l'installation pilote qui attestent la validité des algorithmes élaborés.

An explicit self-tuning controller based on the Takagi-Sugeno fuzzy model of the process is proposed. The fuzzy model is represented as a linear regression model whose parameters are functions of some of the process variables. Such a model can be considered as a linear time-varying model whose parameter values are known at every moment. The pole placement design procedure modified for time-varying systems is applied to obtain the polynomial controller parameters that provide the desired closed-loop poles. The proposed algorithm is very simple, and thus suitable for on-line controller design in adaptive control systems.

This paper presents a modification to the Kandadai and Tien’s learning algorithm for tuning a fuzzy-neural controller that is able to automatically generate a knowledge base. Tuning is based on reinforcements from a dynamical system, thus giving a pseudosupervised learning scheme using error backpropagation. Originally, a weak reinforcement in the form of a binary failure signal was assumed which proved to be insufficient in terms of steady-state error. Therefore, a continuous reinforcement signal is applied enabling the system to correct the error as well as decreasing the overall control effort in the learning phase.
