Abstract
A measurement control system for a multi-shaft supported air floatation platform, the system comprising a load feedback unit (), an execution unit (), a position measurement unit (), a safety protection unit (), a controller (), a rotating motor (), and a linear light source; the load feedback unit comprises M pressure sensors (-) and four differential sensors (-); the execution unit comprises M servo voice coil motors (-) and M servo voice coil motor drivers (-); the position measurement unit comprises a plane grating (-), M linear gratings (-) a linear array CCD (-), a tilt sensor (-), M electronic levels (-), and an indoor GPS (-); the safety protection unit comprises 2M proximity sensors (-) and M temperature sensors (-); and the linear array CCD consists of no few then six CCDs. The system solves the problems of leveling limitations and narrow application range of existing supporting platforms.
