Abstract:
A base stabilization system for controlling motion of a controlled structure said stabilization system comprising:A) a ground structure, B) a base structure on which equipment is mounted said base structure and said equipment comprising said controlled structure, C) a least three air mounts supporting said base structure, D) at least three vertical actuators each of which is attached to said ground structure and to said base structure for controlling vertical motion of said controlled structure, E) a plurality of vertical position sensors one of which is co-located with each one of said at least three vertical actuators for monitoring vertical positions of said base structure relative to said ground structure, F) a plurality of vertical accelerator sensors one of which is co-located with each one of said at least three and one of the position sensors for monitoring acceleration of said base structure, G) a multi-input, multi-output feedback control system comprising a computer processor programmed with a feedback control algorithm for controlling each of said at least three vertical actuators based on feedback signals from each of said vertical position sensors and each of said vertical accelerator sensors said feedback.
