Title:
ACTIVE TYPE VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018036982
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an active type vibration control device which can surely execute adaptive control when there is an operation restriction of a vibration generator.SOLUTION: Vibration on an evaluation point 20 for controlling vibration of a control object vibration dif there is no operation restriction of a vibration generator 30 is represented by ideal control vibration y2. A control device 60 includes: an ideal filter coefficient update section 69 which updates an ideal filter coefficient C2in an ideal control signal u2for allowing the vibration generator 30 to generate the ideal control vibration y2, by adaptive control; a coefficient limiter 70 which calculates an actual filter coefficient C1based on the ideal filter coefficient C2and a threshold Thcorresponding to the operation restriction; and a control signal generating section 62 which generates a control signal u1based on the actual filter coefficient C1.SELECTED DRAWING: Figure 1
