| Abstract: | Adaptive predictive control problems of networked control systems with network induced delay and data packet dropouts.Considering time-delay and data packet loss exist in sensor-controller channel and controller-actuator channel,a scheme is proposed in controller node to obtain the input-output data by using the capacity of the transmitted data packet sufficiently,and furthermore on-line identify the object model parameters,the identified model is used to design predictive controller.The derivation of the algorithm and the compensation method of time-delay and data packet drop are presented.Experiment study over campus-wide network shows the validity of the proposed control scheme. |
