Quantized Output Feedback Stabilization under DoS Attacks

Quantized output feedback stabilization by Luenberger observers

We study a stabilization problem for systems with quantized output feedback. The state estimate from a Luenberger observer is used for control inputs and quantization centers. First we consider the case when only the output is quantized and provide data-rate conditions for stabilization. We next generalize the results to the case where both of the plant input and output are quantized and where ...

Robust Stabilization of Linear Uncertain Systems via Quantized Feedback

This paper studies the problem of robust stabilization for linear uncertain systems via logarithmic quantized feedback. Our work is based on a new method for the analysis of quantized feedback. More specifically, we characterize the quantization error using a simple sector bound. It is shown in our previous work that this method yields the same result on the coarsest quantization density as in ...

On Control of Linear Systems Using Quantized Feedback

This paper studies a number of control problems for linear systems using quantized feedback. First, we revisit the work by Elia and Mitter on quadratic stabilization of linear systems using quantized state feedback and show that their result on coarsest quantization density can be simply obtained from known quadratic stabilization theory by treating the quantization error as sector-bounded unce...

Observer-based quantized output feedback

This paper addresses the problem of stabilizing a nonlinear system by means of quantized output feedback. A conceptual framework is presented in which the control input is generated by an observer-based feedback controller acting on quantized output measurements. A stabilization result is established under the assumption that this observer-based controller possesses robustness with respect to o...
