丢包网络化控制系统非脆弱量化H∞控制
Non-fragile Quantized H∞ Control for Networked Control System with Packet Dropouts
摘要
Abstract
To address the problem involving a class of nonlinear networked control systems with controller parameter uncertainties,we simultaneously consider sensor-to-controller and controller-to-actuator packet dropouts and quantization errors,and present an approach for designing a non-fragile quantized H∞ controller with additive gain uncertainties.Based on Lyapunov stability theory and linear matrix inequality (LMI),we convert the design of the controller with uncertain gain into a convex optimization problem with linear matrix inequality constraints.We then establish sufiicient conditions for the existence of a non-fragile robust H∞ controller in the case of packet dropouts.The proposed controller is robust and non-fragile,and can assure the stability and H∞ performance of a closed system with a packet-dropout rate,gain perturbation,and quantization density in permitted ranges.Finally,we use a numerical simulation to demonstrate the effectiveness of the proposed approach.关键词
