Abstract For continuous time semilinear control systems with con strained control values stabilizing discrete feedback controls are dis cussed It is shown that under an accessibility condition exponential discrete feedback stabilizability is equivalent to open loop exponential asymptotic null controllability A numerical algorithm for the computa tion of discrete feedback controls is presented and a numerical example is discusse
