Abstract

This paper presents a Delayed Generalized Predictive Controller(DGPC) by internal model for bilateral teleoperation systems inthe presence of both communication delays and force feedback.First, the Pi-freeness algebraic property of mechanical delayedsystems, which presents some similarity with the notion offlatness, is used for the slave system to track a master systemreference trajectory; the DGPC next ensures stability of theglobal slave system in spite of delays, disturbances or the slaveforce feedback (the reference trajectory is not a priori known).Simulation results illustrate the performance of the proposedpredictive polynomial controller.
