Abstract

We present a networked control scheme which uses a model based prediction and time-stamps in order to compensate for delays and packet dropouts in the transmission between sensor and controller and between controller and actuator, respectively. In order to analyze the properties of our scheme, we introduce the notion of prediction consistency which enables us to precisely state the network properties needed in order to ensure stability of the closed loop.
