Firstly, by virtue of Schauder's fixed point theorem, the existence of periodic solutions is given. Secondly, utilizing a generalized Gronwall inequality given by us and the Banach fixed point theorem, the existence and stabilizability of a steady-state for the semilinear control system with pulse-width sampler is also obtained. At last, an example is given for demonstration. KW - pulse-width sampler system KW - compact semigroup KW - steady-state KW - existence KW - stabilizability SN - 1232-9274 ER -
