Abstract:
Platform leveling describes a system or method adopted for leveling w.r.t
horizontal plane. In many applications, platforms/turn tables have to be
leveled before they can be used for instrumentation or other purposes
such as accurate target positioning, Auto-leveling for vehicle-borne
platform, alignment of machinery and construction. Many techniques
have been adopted for leveling of a tilted platform.
This thesis introduces a different technique, namely, soft leveling
technique, which is based on error compensation of tilt in software rather
than physical leveling of platform.
The tilt in the platform is modeled, which is then estimated using an
inclinometer. A least squares approach minimizes discrepancy due to
measurement noise. The results of the proposed scheme as implemented
on a physical system demonstrate the utility and accuracy of the method.
