The world's largest privately owned company for the development of powertrain systems, AVL LIST GmbH, has used MathWorks simulation tools to reduce the development time of their real-time combustion controller by approximately 50% compared to implementation using manual programming.
Engine calibration involves controlling an engine to its optimum combustion position, traditionally a slow process of trial and error with an engine running on the test bed. To address this challenge, AVL has developed a new real-time combustion controller that significant;y reduces test bed time for engine calibration teams.
AVL built a simulated system-level model in Simulink to verify the controller over its full range of operation and test the reaction to limit violations to protect the engine under test. Real-Time Workshop and the AVL ARTE.Lab tool helped the team quickly generate code from the controller model and execute it on the test bed.
In addition to reducing development time, AVL integrated a new test bed with the controller in just two days and cut testing time by 80% on a recent pilot project.
“Using MathWorks simulation tools was critical to the success of our combustion controller, which will, in turn, enable our test bed customers to reduce testing time,” said Product Manager at AVL, Dr. Klaus Rothbart.
“Integrating MathWorks simulation tools gives us an advantage because a majority of our customers also use MATLAB and Simulink, and can customise the combustion controller without additional ramp-up time,” adds Dr. Rothbart.
