Abstract:
1. A vibration controller for active vibration insulators, the vibration controller comprising: a map controller including a data map storage for storing data on control signals determined in advance for a vibration insulator disposed on a vehicle, and a signal generator for selecting one of the data from the data map storage and generating a control signal, the one of the data depending on a frequency of a cyclically pulsating signal emitted from a vibration generating source of the vehicle; an adaptive controller for generating the control signal with respect to the cyclically pulsating signal, the control signal based on an adaptive control method; set-up frequency judging-and-switching means for switching from the map controller to the adaptive controller or vice versa based on the frequency of the cyclically pulsating signal, whereby letting one of the map controller and the adaptive controller generate the control signal; and means for actuating an actuator of the vibration insulator based on the control signal generated by one of the map controller and the adaptive controller, whereby inhibiting the vehicle from vibrating by means of vibrating forces exerted by the vibration insulator.
