Abstract
We present results on changing supply rates for input-output to state stable (IOSS) discrete-time nonlinear systems. Our results can be used to combine two Lyapunov functions, none of which can be used to verify that the system has a certain property, into a new Lyapunov function from which the property of interest can be concluded.We present several applications of our results to discrete-time systems such as a l_a Lasalle criteria for input to state stability (ISS) and input to state stability with positive semide_nite Lyapunov functions.
