Variable Deadband Sampling and T-S fuzzy PID co-design for Optimizing QoS and QoP of Wireless Networked Control Systems

摘要

Variable deadband sampling is used in wireless networked control systems to reduce the network message. In this paper the T-S fuzzy PID with variable deadband sampling is designed to optimize the quality of network services and the quality of control performance in closed control loop. Furthermore, Kalman filtering algorithms dealing with variable deadband sampling are considered in the paper. The comparison results of proposed method and PID with period sampling are presented based on the extensive simulations by using TrueTime 1.5 toolbox for Matlab/simulink, and the simulation results verify the effectiveness of the proposed method.
