Abstract

We investigate a state feedback synthesis problem involving saturating inputs via circle criterion. The closed-loop fuzzy system is asymptotically stable in the presence of sector-bounded saturating inputs. The problem is tackled via the famous circle criterion borrowed from system theory. We present results in a unified fashion applicable to both continuous- and discrete-time problems. Finally the validity and applicability of the approach are demonstrated by an example.
