We present sufficient conditions that guarantee that if a controller achieves integral input-to-state stability (iISS) of an approximate discrete-time model of a nonlinear sampled-data system, then the same controller will achieve semiglobal practical iISS of the exact discrete-time model by reducing the sampling period. Results are presented for arbitrary dynamic controllers that can be discontinuous in general.
