Patent number: 11596977Abstract: A vibration control device of a plate-like member 11 includes: a plurality of piezoelectric element actuators 14; at least one piezoelectric element sensor 15; and a control circuit 17 that performs feedback control of operation of the piezoelectric element actuators 14 based on an output voltage of the piezoelectric element sensor 15 so as to suppress vibration of the plate-like member 11. A layout of the piezoelectric element sensor 15 and the piezoelectric element actuators 14 is set such that anti-resonance occurs in an output voltage of the piezoelectric element sensor 15 in a range where the vibration frequency of the plate-like member 11 is equal to or less than a predetermined value. Therefore, generation of noise can be prevented at the frequency. As a result, a gain can be increased at a control target frequency. Therefore, vibration can be suppressed, and noise can be reduced.Type: GrantFiled: December 23, 2019Date of Patent: March 7, 2023Assignee: HONDA MOTOR CO., LTD.Inventors: Shunji Suzuki, Toshizumi Yamaguchi

Publication number: 20200212287Abstract: A device for damping a plate-shaped member includes a piezoelectric element actuator, a piezoelectric element sensor, and a control circuit which carries out feedback control of operation of the piezoelectric element actuator based on an output voltage from the piezoelectric element sensor so as to suppress vibration of the plate-shaped member. The control circuit includes a low pass filter which reduces a high frequency gain of a voltage inputted into the piezoelectric element actuator in a region in which a vibrational frequency of the plate-shaped member is a predetermined value or greater. Therefore, amplification of vibration in such a frequency region can be suppressed. Accordingly, a feedback gain is increased by a control objective frequency, so that vibration can be suppressed, and noise accompanying the vibration can be reduced.Type: ApplicationFiled: December 6, 2019Publication date: July 2, 2020Inventors: Shunji Suzuki, Toshizumi Yamaguchi

Publication number: 20200208710Abstract: A vibration control device of a plate-like member 11 includes: a piezoelectric element actuator 14 and a piezoelectric element sensor 15 fixed to a surface of a plate-like member 11; and a control circuit 17 that performs feedback control of operation of the piezoelectric element actuator 14 based on an output voltage of the piezoelectric element sensor 15 so as to suppress vibration of the plate-like member 11. The control circuit 17 applies any voltage in a range where a vibration frequency of the plate-like member 11 is equal to or less than a predetermined value based on characteristics of an output voltage of the piezoelectric element sensor 15 so as not to generate noise in a range of 100 Hz or less. Therefore, by increasing a feedback gain, vibration can be suppressed, and noise generated by the vibration can be reduced.Type: ApplicationFiled: December 23, 2019Publication date: July 2, 2020Applicant: HONDA MOTOR CO., LTD.Inventors: Shunji Suzuki, Toshizumi Yamaguchi
