Second-order Sliding Mode Control for Offshore Container Cranes
Open-sea stevedores of containers provide an alternative way to avoid port congestion. This process involves a mobile harbour equipped with a crane which loads/unloads containers from a large cargo ship. However, the presence of ocean waves and gusty winds can produce an excessive sway to the hoisting ropes of the crane system. This paper presents a second-order sliding mode controller for traj...

متن کاملHybrid control of container cranes
Hybrid cranes use ultracapacitors to store energy that is regenerated when lowering a container or during braking, and reuses this energy to assist the engine later on. A hybrid crane needs a system that optimizes the fuel cost by controlling in real time the two available power sources. Currently, the crane uses a rule-based heuristic strategy, which does not achieve optimal results and is dif...
متن کاملOffshore Container Crane Systems with Robust Optimal Sliding Mode Control
Open-sea ship-to-ship transfer operation is an alternative way to avoid port congestion. This process involves a relatively small vessel which transports containers between the harbour and a large cargo ship equipped with a container crane. However, the presence of disturbances and uncertainties caused by harsh open-sea conditions can produce an excessive sway to the hoisting ropes of the crane...
متن کاملPort Automation: Modeling and Control of Container Cranes
The container crane is a key machine in ports. Over the past 15 years, modeling and control of quay cranes for automating ports has been the main research issue. In this paper, crane models and control methodologies appeared in the literature are reviewed. A generalized formulation of the most widely used crane model is introduced. Various control techniques are briefly discussed. In conclusion...
