On the absolute stability approach to quantized feedback control:Further insight
By exploring some geometric properties of the logarithmic quantizer and using the fact that the logarithmic quantizer is sector bounded and nondecreasing,this paper presents a new approach to the stability analysis of quantized feedback control systems.Our method is based on Tsypkin-type Lyapunov functions that have been widely used in absolute stability analysis problems.The results are expressed in linear matrix inequalities(LMIs)and are valid for both single-input and multiple-input discrete-time linear systems with a logarithmic quantizer.Theoretical analysis shows that the results in this paper are generally less conservative than those in the quadratic framework.
