A passive-adaptive vibration control system is provided wherein various elements of the system may be adapted on-line in response to sensed vibrations. A spring/weight vibration absorber (160, 165) is attached to a vibrating body, such as the drum (115) of a laundry machine (100), to absorb energy generated by the drum, to minimize the transmission of vibrations to a structure, such as the body of the machine (100) in mechanical communication with the drum. The mass of the weight (160) of the vibration absorber may be adjusted, on-line, to compensate for sensed vibrations. A vibration sensor (170) is connected to the vibrating body so as to sense the level of vibration above a desired level and to send a signal representative of that vibration to an electronic controller (180). The electronic controller (180) is designed to instruct an actuator arrangement (182, 184) to adapt the mass of the weight to compensate for the sensed vibration. For example, the weight (160) may be a chamber, the mass of which may be adjusted by adding or releasing a fluid to or from the chamber via the actuator arrangement (182,184) under the control of the controller (180). <IMAGE> |
