This　paper　discusses　the　impulse　controllability　and　impulse　observability　of　stochastic　singular　systems.　Firstly,　the　condition　for　the　existence　and　uniqueness　of　the　impulse　solution　to　stochastic　singular　systems　is　given　by　Laplace　transform.　Secondly,　the　necessary　and　sufficient　conditions　for　the　impulse　controllability　and　impulse　observability　of　systems　considered　are　derived　in　terms　of　matrix　theory.　Finally,　an　example　is　given　to　illustrate　the　effectiveness　of　the　obtained　theoretical　results.　©　2020,　The　Editorial　Office　of　JSSC　&　Springer-Verlag　GmbH　Germany.
