SRL Modeling Hydraulic Systems Behavior Using Sys. ML Presented to: Dr. Gary May & Dr. Chris Paredis By: Arnaldo J. Colón-López Universidad del Turabo, P. R. Mechanical Engineering Fifth Year 13 August 3, 2005

SRL Overview n n n n Motivation & Objectives What is Sys. ML? HAL System Overview Approach Results Conclusions Summary 14

SRL Motivation & Objectives n How can we support the simulation of system models? ¡ ¡ n n n Save the knowledge about the model in a standard language Create the model once, then reuse rather than recreate the model System Engineers need a standard language to facilitate systems design through the use of reference libraries in Sys. ML. Generate reference and simulation library of components. Create system simulations automatically from configurations of reference models. Make links to simulation models Save money, time and effort 15

SRL n n System Modeling Language “Sys. ML” Sys. ML is a profile and extension of the Unified Modeling Language. Supports the verification and analysis of complex systems. Improves the ability to exchange systems engineering information amongst tools Focuses on engineering systems. 16

SRL HAL System Overview n n n The Hydraulic Actuated Lifter was designed and build in the Intelligent Machine Dynamics Laboratory at Georgia Tech. HAL was designed by two IMDL students, Mimics a forklift truck. Primary purpose is to serve as an educational tool. HAL is constrained by a linear track for safety reasons. 17

SRL Approach n n n n Learn about Sys. ML Develop the hydraulic components library. Describe the HAL system using the Sys. ML tools. Find the best diagram for the system behavior representation. Generate the links for the simulation and reference models. Build the simulation using the Dymola Software. Test the entire design process. 18

SRL Conclusions n Sys. ML is a good language for defining reference models. ¡ ¡ ¡ Sys. ML defines the relation between the reference and simulation models once Reuse the reference model often Saves time & resources. 26

SRL Summary n n Sys. ML is a profile and extension of Unified Modeling Language. Sys. ML was used to provide a standard modeling language for systems engineering to analyze the HAL System. Main Sys. ML Diagrams are: Parametric, Class and Structure diagrams. Artisan Real-Time Studio with Sys. ML supports the representation of system behavior. 27
