Proceedings of 1995 34th IEEE Conference on Decision and Control

Some issues in the stability of difference-delay in the linear and the nonlinear case are investigated. In particular, sufficient conditions are derived under which a system remains stable or unstable, independent of the length of the delay(s). Connections are made to certain Riccati equations and to singular perturbations of discrete maps.
