Unfalsified control for real-time tuning of PID parameters

In this paper, we address "unfalsified control" and its application to decisions of PID parameters with respect to on-line scheme. Here, we expand the results in to PID parameter tuning from the viewpoint of time domain specifications, which enables us to regard as unfalsified control in the practical sense. For the sake of this expansion, we propose new performance functions for unfalsified control, e. g., steady state, transient response and so on. Moreover, by using such functions, we also provide more useful synthesis of unfalsified control. In order to validate the usefulness of our results, we also show an illustrative example.
