Abstract

For analyzing the stability of discrete-time systems containing a feedback nonlinearity the Tsypkin criterion is the closet analog to the Popov criterion which is used for analyzing such systems in continuous-time. Traditionally the proof of this criterion is based upon input-output properties and function analytic methods. In this paper we extend the Tsypkin criterion to multivariable systems containing an arbitrary number of monotonic sector-bounded memoryless time-invariant nonlinearities, along with providing a Lyapunov function proof for this classical result.
