This paper discusses the design of an H∞ MIMO centralized feedback controller applied to a 3 DOF parallel robot namely the “Delta robot”. The designed controller is used in combination with a feed-forward pre-computed torque (a priori torque). The simulation results for a complex trajectory used in pick and place operation with high acceleration (12 G) show the performance improvements obtained by the total controller (a priori torque + H∞ feedback) in comparison to the conventional decentralized PID controller used with the a priori torque.
