Analysis and Model for NCS with Estimator for Data Packet Dropout Compensation

This paper investigates modeling and analysis of networked control systems subject to induced delays and packet loss.In view of the induced delays system existence data packet dropout,we design estimation compensator under the data packet dropout system,using its information to update the output of the controller and building system model,thus we can effectively reduce time-delay and the impact of date packet dropout on the system,and it also can effectively improve the stability performance of control systems.Meanwhile,the stability analysis for the closed-loop system is given by Lyapunov stability theory,and controller design method is given.Finally,passed the example simulation,we confirmed the validity of the design of estimation compensator for networked control systems.
