Abstract

The "harmonic control" algorithm is a well-known method to suppress harmonic disturbances in the active control of vibration. In theory the algorithm should be implemented using a steady-state approach, where the control signal is updated only after the output of the control path has achieved steady-state in response to the previous update. Although some convergence conditions exist for specific forms of instantaneous implementation, recent results obtained by the authors have established conditions for a wide class of harmonic algorithms. In this paper these results are extended to include the case of the simultaneous control of multiple harmonics.
