A generalized approach for the absolute stability of discrete-time systems utilizing the saturation nonlinearity, based on passivity properties

A criterion for the absolute stability of discrete-time feedback systems utilizing the saturation nonlinearity is presented. The criterion is based on the passivity properties associated with the saturation nonlinearity. The present approach is essentially a generalization of an earlier one due to D. Mitra (ibid., vol.CAS-26, no.6, p.365-71, 1978).<
