In particular, the paper considers how the number of actuator speakers affects the performance of the system. The robust controller design methodology being considered is based on some recent results on minimax LQG control. The paper also uses a structured approach to uncertainty modelling as part of the controller design scheme.* This work was supported by the Australian Research Council.6enPublisher Copyright: Copyright © 2002 IFAC.Active noise controlMinimax LQG controlMultiple ActuatorsRobust controlUncertainty modelling200210.3182/20020721-6-es-1901.0037284945578599
