...Wei Zhang; Younan Zhao; Masoud Abbaszadeh; Mingming Ji This paper considers the observer design problem for a class of discrete-time system whose nonlinear time-varying terms satisfy incremental quadratic constraints. We first construct a circle criterion based full-order observer by injecting...
