This article considers the sliding mode control problem with redundant channels, in which the transmitted signals may be subject to the fading phenomenon. First, the censoring strategy is utilized to judge the fading degree of the transmitted signals. If the measurements from the primary channel fail to pass the censorship, the ones from the redundant channel will be examined by the detector. A hold-input compensatory scheme will be adopted if the measurements from all channels are disqualified. Furthermore, a channel-dependent state observer is designed to estimate the unavailable states by taking the redundant transmission and censored measurement into consideration. And then, the channel-dependent sliding mode controller is constructed. Both the stochastic stability of the closed-loop system and the reachability of the specified sliding surface are analyzed, and the corresponding sufficient conditions have been obtained. Finally, the numerical simulation results are provided.
