Upcoming missions to the Moon and Mars are triggering an extensive range of new design techniques and tools to deal with the emerging complexity of the required systems. This webinar presents an overview of modeling and simulation of space systems using physical modeling techniques derived from symbolic model formulation techniques.
Symbolic techniques offer distinct advantages over traditional numerical modeling systems. First, they effectively automate the model development process. Even highly detailed models can be fully developed in just a few days. Additionally, the direct manipulation of model equations, which maintain symbolic mathematical structure throughout the formulation, facilitates key model optimization techniques. This provides significant speed advantages in hardware-in-the-loop (HIL) testing. Finally, full symbolic equations enable advanced design and analysis techniques such as parameter optimization.
To illustrate these techniques, this webinar will present the details of a recent initiative launched at the University of Waterloo (UW), in collaboration with the Canadian Space Agency (CSA), Maplesoft, and the Government of Canada. The project is to develop a full solution for the power management system of robotic rovers, which will be used for upcoming missions to the Moon and Mars. The CSA has a strong history of applying symbolic techniques in space robotics modeling. They have used these techniques in the design of various space robots deployed through the Space Shuttle program and the International Space Station. This new initiative will utilize the latest generation of symbolic modeling technology (e.g. MapleSim from Maplesoft) to rapidly develop high fidelity, multi-domain models of the rover subsystems. The initiative also includes a full range of HIL testing phases and advanced algorithms to optimize system parameters for maximum power conservation while still achieving mission goals.
