Abstract

The objective of this paper is to present a new control design for precisely controlling overhead traveling cranes using microprocessors. Overhead cranes are widely used in manufacturing factories and are currently controlled by human operators. Automatic control can bring a number of important benefits, but existing algorithms tend to result in steady-state positioning errors in the presence of friction. In the proposed control design, a state feedback control algorithm is used to guarantee stability, a trajectory planner used to avoid saturation, and an additional integral term is used to eliminate steady-state error. Theoretical analysis and experimental implementation on a laboratory crane verifies the effectiveness of the approach.
