Abstract : This paper is concerned with the problem of ﬁnite-time H∞ control for stochastic singular systems with partly known transition rates (TRs). The transition of system parameters follows a ﬁnite-state Markov process. Firstly, based on stochastic functional method and linear matrix inequalities (LMIs) technique, sufﬁcient conditions are proposed to ensure ﬁnite-time stochastic boundedness (FTSB) and ﬁnite-time H∞ stochastic boundedness (FTH∞SB) of considered stochastic singular system. Secondly,by designing a state feedback controller,strictLMI conditions are obtained to guarantee the closed-loop system with partly known TRs to be FTSB and FTH∞SB. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed methods.
