Abstract

In many applications, platforms/turn tables have to be leveled before they can be used for instrumentation or other purposes. In this paper, we introduce a soft leveling technique, which is based on error compensation rather than physical leveling. 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.
