Abstract | |||||||||||||||||
| This paper is concerned with global asymptotic stabilization of continuous-time systems subject to quantization. A hybrid control strategy originating in earlier work (R. W. Brockett and D. Liberzon, Quantized feedback stabilization of linear systems, IEEE Trans. Automat. Control, 45:1279-1289, 2000) relies on the possibility of making discrete on-line adjustments of quantizer parameters. We explore this method here for general nonlinear systems with general types of quantizers aecting the state of the system, the measured output, or the control input. The analysis involves merging tools from Lyapunov stability, hybrid systems, and input-to-state stability. | |||||||||||||||||
