3 Hours


Conventional engineering modeling software packages are reaching the limits of their usefulness for emerging modeling challenges, such as the multidomain systems found in robotics, green engineering, and hybrid vehicles. This Workshop and Tutorial offers practical insights and techniques for overcoming these modeling challenges. Using the modeling software MapleSim, attendees will learn how to quickly develop high fidelity models of multidomain physical systems. The application focus will be control system development with a special emphasis on plant modeling and HIL testing. The techniques and examples are drawn from real industrial and research applications in automotive, aerospace, and robotics among others.
The conventional plant modeling process requires extensive effort on the part of the engineer in the form of manual derivation and manipulation of equations, and implementation of those equations in a signal-flow representation. Physical modeling in MapleSim provides an intuitive interface for constructing complex models from components. MapleSim also allows direct access to all of the model equations that are automatically generated and maintained in symbolic form, thus avoiding the error-prone process of manual derivation. Model development time can be significantly reduced – in many cases from months to days.
One further consequence of the MapleSim approach is increasing the fidelity of plant models for Hardware In the Loop (HIL) simulation while maintaining very fast real-time computation speeds. Using symbolic algorithms, model equations can be simplified and then converted into highly optimized source code that can run significantly faster than models and code developed with other software systems.


Attendees can expect to obtain a comprehensive introduction to MapleSim and the physical modeling process during this half-day tutorial. This will include:
• Familiarity with the MapleSim environment (approximately 1 hour)
• Physical modeling capabilities to create models from the ground up (approximately 1 hour)
• Skills and techniques to investigate and analyze model behaviour upon simulation (approximately 1 hour)
• Conclusion and Questions (approximately 30 minutes to 1 hour)

Background Knowledge Expected of the Participants

Attendees are not required to be familiar with the MapleSim or Maple environments. It is recommended that attendees have basic experience or knowledge of modeling concepts from at least one engineering domain (such as electrical, mechanical, multibody, etc.).

Qualifications of the Instructor(s)s

Dr. Enzo Bergamini. After a BSCS in Computer Science, I worked for 12 years as a researcher and ICT manager at a private automotive research center. From 2001 I'm following the business development and the technical support for Maplesoft tools at Teoresi, the Italian local reseller.

Dr. Dayana Pesando obtained her PhD in Applied Mathematics from the University of Nottingham in United Kingdom in 2011. She is currently working as an Engineer at Teoresi SpA in Italy in the Automotive business unit. Her fields of interest are mathematical modeling and simulation using software such as Maple and MapleSim.
