Title:
能動型振動騒音抑制装置
Document Type and Number:
Japanese Patent JP6657047
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an active type vibration noise suppression device capable of suppressing either vibration or noise at an evaluation point stably and easily even if either a sensor or an actuator is not installed at the evaluation point.SOLUTION: Control units 60, 160 comprise a reference control vibration generation part 66 producing a virtual reference control vibration y2; a reference filter coefficient update part 69 updating a reference filter coefficient C2by adaptive control so as to reduce error between an object vibration dat an error detecting point 20 and the reference control vibration y2; a real filter coefficient calculation part 71 for calculating a real filter coefficient C1on the basis of a reference filter coefficient C2and an adjustment coefficient corresponding to a transmittance function B from the error detecting point 20 to an evaluation point 80; and a control signal generating part 62 for generating a control signal u1on the basis of the real filter coefficient C1.SELECTED DRAWING: Figure 4
