Abstract :
We consider harmonic steady-state (HSS) control for active noise and vibration rejection when the system dynamics are unknown. After a brief review and analysis of the HSS control theory, we develop an adaptive control algorithm based on a recursive least squares algorithm that estimates the system dynamics. Active noise cancellation in an acoustic drum is demonstrated using the adaptive control algorithm. The results presented here unify and extend previous results on HSS control
