Design of Quantized Feedback Control of Networked Control Systems with Nonlinear Perturbation

Aiming at the networked control systems(NCSs) with network-induced delay,data packet drop-out and nonlinear perturbation,a new general model of NCSs is developed taking account of such disturbance as quantized error and nonlinear perturbation.Based on principle of Lyapunov stability and method of linear matrix inequality,the sufficient condition is given to make the NCSs asymptotically stable with the design method of a quantized feedback controller proposed.Maximum allowable delay bounds of NCSs with nonli...
