Title:
VIBRATION-NOISE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3751359
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a vibration-noise transmission characteristic of high accuracy following aged deterioration and the like without outputting an identification signal itself.
SOLUTION: Adaptive control circuits 201, 202 provided in a DSP 12 has vibration control parts 241, 242 and identification processing parts 251, 252. The identification processing parts 251, 252 has built-in H-system identification filters 291, 292 and C-system identification filters 311, 312 modeled after real systems. Genetic algorithm(GA) processing parts 30, 32 are provided to identify an H- system dynamic characteristic and a C-system dynamic characteristic. System identification is performed by updating coefficients so that the deviation between false error signals ε" from the identification processing parts 251, 252 and an error signal ε from a vibration error sensor 9 is the minimum value. The identification result of the C-system identification filters 311, 312 is copied on C-filters 271, 272 and used at the time of updating the coefficients of W-filters 261, 262.
