Equation Based Modelling:

  • Easiest and fastest

For power train components:

Not much information needed to input to get useful info from graphs and a check if parts will work

  • Powertrain components are built using smaller components

  • Can look in each model for details about how it is being modeled

  • Can override specific parts (ex: specific analysis of batteries or motors)

  • Can generate code and put them in simulator for hardware testing

  • Made with MatLab project and helps organize everything

  • inside the motor component

  • can also switch to more complicated motor model

  • can consider effects during certain maneuvers

  • don’t care about pitch or roll of vehicle

  • start considering yaw, turns

  • Everything being considered - 14 degrees of freedom

  • Models suspension in lots of detail

  • Can’t model custom vehicle rn in 3D but can use a different car model to see

  • red dots = target path

  • Can make lidar point cloud generation

  • Get camera output

  • For multidomain systems: combination of systems (mech, electrical, etc)

  • There’s also a simscape language to create custom blocks/components

  • Those blocks can use same equations as earlier

  • Automatically creates direction between components

Simple multidomain system

  • Includes friction and load torque in system

  • Simscape will derive equations

  • Lots of add-ons

  • Multi-body simulation

  • Starter models for solar components

  • Plot from above slide!

  • can use data from battery cells and develop Simscape model

  • Mechanical Systems

  • Can import CAD geometry

  • 4 post test rig

  • Uses simplified CAD geometry

  • Similar to what’s used in industry

  • Can get 3D representation of force on test rig

    • Can combine the different models/toos

  • Can import and export C/C++ code from simulink

Useful tutorial links

  • They also have Onramp courses for more in depth areas, signal processing, control design, machine learning, etc.

  • more resources in discord

Question: Is there a way to work collaboratively on the cloud

Answer: For smaller stuff, can use MatLab drive. For larger stuff, not really, but using projects is really helpful and can incorporate version control.
