Abstract:
A multidimensional feedback system is used to reduce the noise component of a vibrational or acoustic field. The feedback algorithm includes a matrix operator that diagonalizes the feedback system. As a consequence, each of two or more actuators can be treated as though it closes an independent, one-dimensional feedback system. Therefore, classical one-dimensional feedback analysis can be used in the context of a system having multiple error sensors and multiple actuators.
