In this webinar we will demonstrate how to configure models containing Simscape physical networks to run in real time. We will explain the tradeoff of simulation speed and accuracy in real-time simulation, and explain the settings you can adjust to balance this tradeoff. The demonstration is performed on a model of a pneumatic actuation system, but the concepts have been applied to models spanning hydraulic, electrical, mechanical, and other physical domains.
This webinar will include demonstrations and explanations to show:
• The challenge of moving from desktop simulation to real-time simulation
• How to choose a fixed-step solver
• Why fixed-cost simulation is critical for real-time simulation and how to configure a fixed-cost simulation
• How MATLAB can be used to accelerate this process
• Advances in Simscape that make it easier to get models to run in real-time
Real-time simulation of multidomain physical system models (mechanical, electrical, hydraulic, etc.) requires finding a combination of model complexity, solver choice, solver settings, and real-time target that permit execution in real time. A better understanding of the tradeoffs involved in each of these areas makes it easier to achieve this goal and use Model-Based Design to reap the benefits of using virtual systems prior to building hardware prototypes.
In this webinar we use xPC Target as our real-time simulation platform, but the concepts and settings described in this webinar apply to other real-time platforms as well. In this webinar, we do not focus on the selection of real-time hardware.
