Anytime Control with Markovian Computation and Communication Resources

Wanchun Liu, Daniel E. Quevedo, Yonghui Li, Branka Vucetic

We investigate a novel anytime algorithm for wireless networked control with random dropouts. The controller computes sequences of tentative future control commands using time-varying (Markovian) computation resources. The sensor-controller and controller-actuator channel states are spatial- and time-correlated and are modeled as a multi-state Markov process. We develop a novel cycle-cost-based approach to obtain conditions on the nonlinear plant, controller, network and computation resources that guarantee stochastic stability of the plant.
