The algorithms used for adaptive feedforward control often require a model of the acoustic plant being controlled to update the signals driving the secondary sources. This paper describes the effect of practically realistic plant estimation errors on the stability and performance of such a control algorithm. We have considered the structured plant errors due to changes in the error sensors location, changes in the secondary sources location and drift in the excitation frequency. These errors have very different effects on the stability and performance of the control system. The characteristics of each types of plant error are examined by singular value decomposition of the transfer matrix.
