A load position observer for cranes with gyroscope measurements
نویسندگان
چکیده
In crane automation systems, precise knowledge of the load position is a key factor for fulfilling positioning accuracy requirements. This contribution presents a nonlinear observer design for harbor cranes which makes use of gyroscope measurements. Both single-pendulum load configurations and more complex double-pendulum configurations are considered. The gyroscope sensors are attached to the rope near the top rope suspension point in both cases. The observer is implemented as an Extended Kalman Filter. The results are compared to RTK-GPS reference measurements.

Gyroscope Drift Error Analysis in the Position-Independent Navigation Algorithm of a stable platform Inertial System
This paper deals with analyzing gyroscope drift error in the position-independent navigation algorithm of a stable platform inertial system. Most of the stable platform navigation algorithms proposed in the literature have drawbacks of estimating position rates for alignment commands. Not only the estimating position rates are the basic source of position errors, but they also make the alignmen...
