Abstract
En 中文
This paper investigates the sliding mode control (SMC) problem under finite-bit constrained channels by proposing a co-design framework that integrates a multi-node weighted try-once-discard (WTOD) protocol with a dual-mode dynamic coding scheme. Firstly, a novel multi-node WTOD protocol is developed using an iterative exclusion mechanism, overcoming the single-node limitation by selecting multiple nodes with the most significant weighted errors for simultaneous transmission. Then, a dual-mode coding scheme is proposed that reallocates bandwidth between the quantized state and the scaling parameter according to scaling parameter saturation, while incorporating configurable quantizers with selectable mid-tread/mid-rise structures. Furthermore, a token-dependent sliding mode controller is designed to ensure reachability and stability, establishing an explicit relationship between the minimum coding error bound and both system convergence and sliding domains. Finally, simulation results validate the proposed approach on a third-order DC motor system.
