Hybrid feedback stabilization of systems with quantized signals
نویسنده
چکیده
This paper is concerned with global asymptotic stabilization of continuous-time systems subject to quantization. A hybrid control strategy originating in earlier work (Brockett and Liberzon, IEEE Trans. Automat. Control 45 (2000) 1279) 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 a:ecting 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. ? 2003 Elsevier Ltd. All rights reserved.

On feedback stabilization of nonlinear systems under quantization
The aim of this note is to show how the results in D. Liberzon, “Hybrid feedback stabilization of systems with quantized signals”, Automatica , 39, 1543-1554, 2003, concerning asymptotic stabilization using quantized feedback, still hold under the assumption of asymptotic stabilizability only. As a consequence, we are able to examine as special interesting cases nonlinear systems which are e.g....
متن کاملStabilization by Quantized State or Output Feedback: a Hybrid Control Approach
This paper deals with global asymptotic stabilization of continuous-time systems with quantized signals. A hybrid control strategy originating in earlier work 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 affecting the state of the system or the measured output.
متن کاملNonlinear Stabilization by Hybrid Quantized Feedback
This paper is concerned with global asymptotic stabilization of continuous-time control systems by means of quantized feedback. For linear systems, a hybrid control strategy for dealing with this problem was recently proposed by Roger Brockett and the author. The solution is based on making discrete on-line adjustments to the sensitivity of the quantizer. In the present paper we extend this met...
متن کاملQuantized feedback stabilization of linear systems
This paper addresses feedback stabilization problems for linear time-invariant control systems with saturating quantized measurements. We propose a new control design methodology, which relies on the possibility of changing the sensitivity of the quantizer while the system evolves. The equation that describes the evolution of the sensitivity with time (discrete rather than continuous in most ca...
متن کاملBoundary Feedback Stabilization of a Nonlinear Flexible Gantry Manipulator Using Disturbance Observer
This paper aims to develop a boundary control solution for a single-link gantry robot manipulator with one axis of rotation. The control procedure is considered with link’s transverse vibrations while system undergoes rigid body nonlinear large rotation and translation. Initially, based on Hamilton principle, governing equations of hybrid motions as a set of partial differential equations...
