具有均匀量化器的网络控制系统的一致有界性
Uniformly Bound of Networked Control Systems with Uniform Quantizer
摘要
Abstract
Networked control systems(NCS) with continuous plant and a shorter delay than one sampling period was described by a discrete model. A sufficient condition of stability for NCS neglected the quantization error was derived by Lyapunov method and linear matrix inequality approach. Moreover,a state feedback controller was designed to ensure the NCS with uniform quantizer to be uniformly bounded, and the upper bound of NCS was obtained by accommodating the quantizer error. Quantized level and code length could be obtained in practice. At last,a matlab simulation example was given to illustrate the effectiveness of the proposed method, and the effect of quantized error was analyzed.关键词
