We present a general and unified framework for the design of nonlinear digital controllers
using the emulation method for nonlinear systems with disturbances. It is shown that if a
(dynamic) continuous-time controller, which is designed so that the continuous-time closed-
loop system satisfies a certain dissipation inequality, is appropriately discretized and
implemented using sample and zero-order-hold, then the discrete-time model of the closed-
loop sampled-data system satisfies a similar dissipation inequality in a semiglobal practical …
