On Dynamic Logarithmic Quantizer Design for Continuous Time Linear Systems

This paper addresses logarithmic quantizers with dynamic sensitivity design for continuous time linear system with a quantized feedback control law. The dynamic of the sensitivity during “Zoom-in” / “Zoom-out” stages is proposed. It is shown that with the proposed algorithm, a linear system can be stabilized by quantized feedback control via adopting sensitivity varying algorithm. It is shown that the advantage of logarithmic quantization is sustained while achieving stability. At the end of this paper the results will be verified by simulation.
