Title:
VIBRATION NOISE CONTROLLER
Document Type and Number:
Japanese Patent JP2770286
Kind Code:
B2
Abstract:
PURPOSE: To provide the vibration noise controller which can be improved in converging speed more by reducing an arithmetic load, etc.
CONSTITUTION: In a C table 36, the phase shift quantity ΔP and amplitude gain variable Δa of a transmission system corresponding to the generation timing of variable sampling pulses Psr are retrieved, and the shift quantity ΔP is inputted to an R table 35. The R table 35, on the other hand, outputs a sine wave and a delayed sine wave which is a quarter cycle delayed behind the sine wave each time a variable sampling pulse Psr is inputted and also outputs basic reference signals R'(1) and R'(2) on the basis of the shift quantity ΔP; and the amplitudes of the basic reference signals R'(1) and R'(2) are amplified with a gain variable Δa and the reference signals R(1) and R(2) which are thus amplified are inputted to an LMS process part, which updates the coefficient of a W filter 37 consisting of two taps and calculates the sum of the products of the standard signals U(1) and (2) to generate a control signal V.
