Abstract: A simulation model of wireless networked control system was established on the basis of TrueTime and Matlab/Simulink,and some simulation experiments were performed based on the system model and control strategies.A Fuzzy-PD controller was designed,and a method of parameter optimization off-line was proposed by using ITAE as an important reference index.The control performance was improved by adjusting the converted parameter of the Fuzzy-PD controller based on different network bandwidth occupied rates.The advantage of the Fuzzy-PD control algorithm was validated as compared with PD and Fuzzy control algorithm by the simulation results.
