The guaranteed cost control problem is tackled for a class of networked control systems (NCSs) subject to non-uniform sampling and quantization effect. The sector bound approach is employed to model the effects of logarithmic quantization. A controller with exponential gain is designed to ensure that the cost of the non-uniform sampling system remains within a specified bound, while accounting for all uncertainties and quantization errors. Using the Lyapunov function theory and the Halanay-like inequality, sufficient conditions are established to ensure the exponential stability of the closed-loop system.

摘要

The guaranteed cost control problem is tackled for a class of networked control systems (NCSs) subject to non-uniform sampling and quantization effect. The sector bound approach is employed to model the effects of logarithmic quantization. A controller with exponential gain is designed to ensure that the cost of the non-uniform sampling system remains within a specified bound, while accounting for all uncertainties and quantization errors. Using the Lyapunov function theory and the Halanay-like inequality, sufficient conditions are established to ensure the exponential stability of the closed-loop system.
