A study on autobalancing of a casing oscillator using feedback control

The casing oscillator used for basic construction of buildings, factories, and bridges is a construction machine which rotates and rolls the casing to insert it into the ground. It is very important that the casing is retained at a perpendicular position to sea level regardless of the slope of ground. In this paper, we present a new casing oscillator that does need not to be level to the ground for the casing insertion to work. The kinematic analysis for work space of a casing oscillator is presented and carried out with autobalancing of the casing oscillator using feedback control.
