%X The limited amount of energy in nodes is a critical factor affecting the system performance in wireless networked control systems(WNCS). An adaptive energy scheduling method is proposed to compromise the energy conservation for the nodes and the energy consumption in the control. Based on the relation between the sampling period and the energy consumption, the energy consumption rates are adjusted online to satisfy the requirements of the node-span by employing dynamical sampling periods. Then, the adaptive sampling WNCS is modeled as a discrete switched system with a temporarily uncertain switching signal. For the system incorporated with the feedback of switched states, the stability is analyzed by using the switched system theory, and the constraints on the controller gains and residence time for the asymptotical stability of the system are derived accordingly. A numerical example validates the proposed approach on Truetime1.5 and MATLAB platforms.
