1. A control system for reducing vibration generated by a vibrating plant including a vibrating component, a structure and a mount for mounting the vibrating component to the structure, the control system comprising:

  • a. means for producing controlled vibrations within the mount;

    b. at least one sensor for sensing the current position of the controlled vibration producing means and developing a signal indicative thereof;

    c. at least one sensor for sensing the vibration being transmitted through the mount from the vibrating component to the structure and developing a signal indicative thereof;

    d. at least one sensor for sensing at least one of the characteristic frequencies at which the vibrating plant operates and developing a signal indicative thereof;

    e. a first controller receiving as input the position signal developed by the controlled vibration producing means sensor and generating an output signal;

    f. a second controller receiving as input the transmitted vibration sensor signal and the characteristic sensor signal and generating an output signal; and

    g. means for combining the output signals from the first and second controllers into a control signal for controlling the vibration producing means such that the vibration transmitted from the vibrating component to the structure through the mount is reduced.
