Abstract

The problem of quantization-dependent stability and guaranteed cost control for a class quantized feedback networked control systems(QFNCSs) with the bounded quantization errors are studied. By using the Lyapunov-Krasovskii function and Linear Matrix Inequality (LMI) technique, a sufficient condition for stability and stabilization of QFNCSs is presented, the most signify-cant feature is to given a unified study of quantization and delay effects in QFNCSs. An illustrative example shows the effectiveness of the proposed method.
