From FRIT of a PD feedback loop to process modelling and control system design

This paper discusses a PD(Proportional and Derivative) feedback loop design method from single-shot input and output data based on FRIT(Fictitious Reference Iterative Tuning), and also discusses an estimation method for the process model and a design application for a MD-PID (Model Driven) control system and a TDOF(Two Degrees Of Freedom) PID control system. Numerical examples show the effectiveness of the approach.
