Abstract :
The paper considers the controller design process in the problem of robust active noise control in an acoustic duct. In particular, the paper looks at how differences in system identification and actuator location affects the disturbance attenuation performance of the resulting control system. The robust controller design methodology being considered is based on some results on minimax LQG control.
