A Benchmarking Framework for Control Methods of Maritime Cranes Based on the Functional Mockup Interface
Sanfilippo, Filippo; Hatledal, Lars Ivar; Pettersen, Kristin Ytterstad; Zhang, Houxiang (Journal article, 2017)A benchmark framework for advanced control methods of maritime cranes is presented based on the use of the functional mockup interface. The system integrates different manipulator models, all the corresponding hydraulic ... -
A Language and Platform Independent Co-Simulation Framework Based on the Functional Mock-Up Interface
Hatledal, Lars Ivar; Styve, Arne; Hovland, Geir; Zhang, Houxiang (Journal article; Peer reviewed, 2019)The main goal of the Functional Mock-up Interface (FMI) standard is to allow the sharing of simulation models across tools. To accomplish this, FMI relies on a combination of XML-files and compiled C-code packaged in a zip ... -
A Software Architecture for Simulation and Visualisation based on the Functional Mock-up Interface and Web Technologies
Hatledal, Lars Ivar; Schaathun, Hans Georg; Zhang, Houxiang (Chapter, 2015)This paper presents a software architecture for a collaborative virtual environment (CVE) for simulation and visualisation based on the Functional Mock-up Interface (FMI) for co-simulation and web technologies. FMI has ... -
A Voxel-Based Numerical Method for Computing and Visualising the Workspace of Offshore Cranes
Hatledal, Lars Ivar; Sanfilippo, Filippo; Chu, Yingguang; Zhang, Houxiang (Chapter; Peer reviewed, 2015)Workspace computation and visualisation is one of the most important criteria in offshore crane design in terms of geometry dimensioning, installation feasibility and operational performance evaluation. This paper presents ... -
An Object-Oriented Modeling Approach to Virtual Prototyping of Marine Operation Systems Based on Functional Mock-Up Interface Co-Simulation
Chu, Yingguang; Hatledal, Lars Ivar; Æsøy, Vilmar; Ehlers, Sören; Zhang, Houxiang (Journal article; Peer reviewed, 2018)This paper presents an object-oriented modeling (OOM) approach to model development of marine operation systems, specifically the hydraulic systems of marine cranes. Benefited from the rapid development of computation ... -
Controlling Kuka Industrial Robots : Flexible Communication Interface JOpenShowVar.
Sanfilippo, Filippo; Hatledal, Lars Ivar; Zhang, Houxiang; Fago, Massimiliano; Pettersen, Kristin Ytterstad (Journal article, 2015)JOpenShowVar is a Java open-source cross-platform communication interface to Kuka industrial robots. This novel interface allows for read-write use of the controlled manipulator variables and data structures. JOpenShowVar, ... -
