Coding-Decoding-Based Sliding Mode Control for Discrete Uncertain T-S Fuzzy Systems with Time-Varying Delays

This paper explores the sliding mode control (SMC) scheme for delayed Takagi-Sugeno (T-S) fuzzy systems under resource-constrained channels. In response to the issue of limited communication network resources, a two-step encoding scheme is designed to achieve the adaptive adjustment of encoding errors. Subsequently, a common sliding surface is designed and a new SMC law including the information of encoding errors is given. Next, sufficient criteria for system stability and reachability of the sliding surface are provided. Finally, we demonstrate the effectiveness of the proposed SMC algorithm through a simulation example.
