Abstract :
Model based predictive control over wireless sensor and actuator networks is considered. To deal with time varying round trip latencies and data dropout it is proposed a formulation where the true open loop networked system dynamics is approximated using recursive identification techniques based on the dual unscented Kalman filter. Experimental results using a testbed show the relevance of the implemented approach.
