A new method of the parameter tuning of PID controllers based on least squares method with one-shot closed loop experimental data

Abstract

In this talk, we provide a new method for tuning of parameters of a PID controller by using the least squares method applied to one-shot closed loop experimental data without system identifications.The method we give here has a practical advantage in the sense that what we require is only one-shot experimental data obtained from the closed loop and what we have to do is to perform the well known least squares method.Together with the proposal of a new method and algorithms, we dicuss the issues on the optimality of the obtained parameters and we give an illustrative example in order to show the validity of our result.
