Abstract

En 中文

• A uniform quantization method is employed to encode the discrepancy between the observer state data and the duplicator decoded output into a set of codewords for transmission. This approach not only optimizes the utilization rate of bandwidth but also guarantees the security of information transfer inside the transmission channel. Moreover, the design of the duplicator is aimed at addressing the time and physical constraints imposed by the communication network. • By selecting the appropriate coding interval, coding area, and divisor, the channel capacity is quantitatively analyzed, and a theoretical framework for the coding-decoding scheme is established. Criteria for ensuring system detectability are derived based on this framework. • Utilizing the decoded data obtained from the coding-decoding scheme, an observer-based controller is designed, and sufficient conditions for the strict convergence of the estimated error system are derived. By constructing moderelated Lyapunov functions and combining them with the linear matrix inequality method, the closed-loop system is ultimately exponentially mean-square bounded.
