Considering the characteristics in wireless networked control systems(WiNCS), limited network bandwidth,
limited node energy and high network collision probability, the signal difference-based transmission deadband is set up
in sensors and controllers to reduce network collision and node energy consumption. Then, with the consideration of the
probability distribution of delay in some intervals and parametric uncertainties, a model of WiNCS is established based on
transmission deadband, and the H∞ controller is designed. Results of the semi-physical simulative experiments with real
wireless network and simulative controlled plant show that the network traffic of sensors and controllers is reduced obviously
by using the proposed approach on the basis of the system asymptotical stabilization.
