A less‐conservative stability criterion for networked control systems with time‐varying packet delays

open access: yesIET Control Theory & Applications, 2021
A networked output feedback loop subject to packetized transmissions of the output signal is considered. Based on the small gain theorem, an easy‐to‐use stability criterion covering two important cases is presented.
