Quantized Output Feedback Stabilization by Luenberger Observers

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 ...

Quantized Output Feedback Stabilization under DoS Attacks

This paper addresses the stabilization of quantized linear systems under Denial-of-Service (DoS) attacks. Using a state transformation that satisfies a certain norm condition, we first propose an output encoding method that achieves the stabilization of systems with finite-data rates only under an assumption on the duration of DoS attacks. Next we add a condition on the frequency of DoS attacks...

Quantized Output Feedback Stabilization of Switched Linear Systems

This paper studies the problem of stabilizing a continuous-time switched linear system by quantized output feedback. We assume that the quantized outputs and the switching signal are available to the controller at all time. We develop an encoding strategy by using multiple Lyapunov functions and an average dwell time property. The encoding strategy is based on the results in the case of a singl...

Input-to-State Stabilization with Quantized Output Feedback

We study control systems where the output subspace is covered by a finite set of quantization regions, and the only information available to a controller is which of the quantization regions currently contains the system’s output. We assume the dimension of the output subspace is strictly less than the dimension of the state space. The number of quantization regions can be as small as 3 per dim...
