Quantized output feedback stabilization by Luenberger observers
For control theorists, this paper provides data-rate conditions for quantized output feedback stabilization using Luenberger observers, but the results are incremental over existing work.
This paper studies stabilization of systems with quantized output feedback using Luenberger observers, providing data-rate conditions for stabilization when only the output is quantized and when both input and output are quantized. Numerical comparisons with prior work and a time response of an inverted pendulum are presented.
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 controllers send the quantized estimate of the plant output to encoders as quantization centers. Finally, we present the numerical comparison of the derived data-rate conditions with those in the earlier studies and a time response of an inverted pendulum.
