Stochastic Analysis and Control of Real-Time Systems with Random Time Delays

Johan Nilsson, Bo Bernhardsson, Björn Wittenmark


The paper discusses modeling and analysis of real-time systems subject to random time delays in the communication network. A new method for analysis of existing schemes is presented. The method is used to evaluate different suggested schemes from the literature. A new scheme for handling the random time delays is then developed and successfully compared with previous schems. The new scheme is based on stochastic control theory and a separation property is shown to hold for the optimal controller.
