Title: Innovations in Crane Control: The Contributions of Sebastian Kuchler

Introduction

Sebastian Kuchler is an accomplished inventor based in Böblingen, Germany. He has made significant contributions to the field of crane control technology, particularly in offshore applications. His innovative approach to compensating heave movements in cranes has garnered attention in the industry.

Latest Patents

Kuchler holds a patent for a groundbreaking invention titled "Crane control with active heave compensation." This invention presents a procedure for compensating the heave movement of offshore cranes. The dynamic model of the compensation actuator, which is a hydraulically operated winch, and the load hanging on a rope are derived. Based on this model, a path-tracking control unit is developed. To address the movement of the ship or watercraft caused by waves, the heave movement is defined as a time-varying disturbance and is analyzed concerning uncoupling conditions. With a model expansion, these conditions are satisfied, and an inversion-based uncoupling control law is formulated. To stabilize the system, an observer is used for reconstructing the unknown state through force measurement. Furthermore, the compensation efficiency can be improved by predicting the heave movement. A prediction method is proposed that does not require ship or watercraft models or properties. The simulation and measurement results validate the heave compensation method.
