VIBRATION ISOLATION SYSTEM AND METHOD

摘要

A system and method for isolating a mass from vibration including an actuator 34 operably connected to the mass 32, the actuator 34 being responsive to a combined control signal 46; a position sensor 36 operably connected to measure position of the mass 32, the position sensor 36 generating a position signal 38; a comparator 51 responsive to the position signal 38 and a position setpoint signal 58 to generate a position error signal 50; and a combination controller 40 responsive to the position error signal 50 to generate the combined control signal 46; wherein the combination controller 40 adjusts the combined control signal 46 to change system characteristics when the position error signal 50 is outside an operating range.
