Adaptive Static Output Feedback Anti-disturbance Quantized Control for Nonlinear Systems with Multi-source Disturbances

Yitong Zhou and Haibin Sun*

Qufu Normal University

Abstract

In this paper, the problem of adaptive static output feedback anti-disturbance quantized control is proposed for nonlinear systems with multi-source disturbances and unknown parameters. Using the output information, the disturbance observer and the adaptive law are constructed. An adaptive static output feedback anti-disturbance quantized controller is designed by combining with the estimated values of the disturbance and unknown parameters, in which a compensation term is introduced to eliminate the influence of quantization error. The stability and H∞ performance are analyzed by using Lyapunov function method. Finally, a simulation example is given to verify the validity of the results.
