Assignee: TECHNICAL MANUFACTURING CORPORATION
Field: Mechanical elements (Mechanical engineering)
Classification: CPC F  G | IPC F  G

Claim 19:
20. A vibration-isolation control system comprising:
a feedback motion sensor to sense motion of an intermediate mass that is configured to isolate vibrations of a base from a payload or payload support;
a feedforward motion sensor to sense motion of the base;
a first signal path to receive and process a first signal from the feedback motion sensor;
a first signal filter in the first signal path to filter the first signal;
a first phase adjuster in the first signal path to change a phase of the first signal;
a first amplifier in the first signal path to amplify the first signal;
a second signal path to receive and process a second signal from the feedforward motion sensor;
a second signal filter in the second signal path to filter the second signal;
a second phase adjuster in the second signal path to change a phase of the second signal;
a second amplifier in the second signal path to amplify the second signal; and
a summer to sum a first processed signal from the first signal path and a second processed signal from the second signal path to produce a drive signal for an actuator that is configured to drive the intermediate mass.
