Abstract
Disturbance feedforward control (DFC) can be used to reject external disturbances that are a priori unknown. This paper addresses the design and performance tradeoffs due to the causal nature of DFC in Multi-Input Multi-Output (MIMO) systems. Performance tradeoffs in optimization over both frequencies and the disturbance directions are expressed in terms of MIMO feedforward sensitivity functions. Design interpretations and disturbance decorrelation are presented to optimize the disturbance rejection properties for systems subject to these fundamental limitations. Simulation studies of a 2- DOF motion stage are included, showing significant performance benefits using disturbance decorrelation.
