Abstract
In this paper, we develop a boundary controller to actively cancel acoustic disturbances
in an enclosed duct of finite length using a loudspeaker. Given a distributed parameter
acoustic model and the actuator electrical dynamics at the boundary, Lyapunov-type
arguments are used to design a model-based backstepping boundary control law that
asymptotically regulates the noise within the duct. Dynamic simulation results demonstrate
the improved performance achieved by the proposed active noise cancellation algorithm.
