Technisch Physische Dienst TNO - TH Publication year 1991 Abstract The generalized minimum variance (GMV) control strategy is proposed as an effective strategy for active sound and vibration control systems. The GMV strategy is shown to unify well-known adaptive filtering approaches based on LMS-type algorithms and purely feedback strategies as used in other types of control systems. The shortcomings of the LMS adaptive filtering systems for active sound control are clearly uncovered. Pure adative filtering emerges from the GMV strategy merely when the extraneous noise at the error sensor is Gaussian noise, the controller complexity is restricted and no fast tracking of system changes is required The necessary additional identification of the secondary acoustic path is an extra problem of the adaptive fittering approach. Simulation experiments with real and synthetic data verify the wide appticability of the GMV control strategy and the limited efficacy of (LMS) adapive filters for use in active sound reduction systems.
