Initializing Parameters 37

Posted by Seth Popinchalk,

Simulink models often use parameters from the MATLAB base workspace.  However, Simulink does not save the MATLAB base workspace with the model.  This leads me to the following question: How do you initialize the workspace for your simulation?... read more >>

Representing Numbers: Integers and Fixed-Point

Posted by Seth Popinchalk,

In embedded systems, computation time and memory are critical resources.  Floating-point calculations require special floating-point units for efficient computation and this translates to processors that are more expensive.  For this reason, designers of embedded systems often use fixed-point numbers.  In this post, I want to introduce the basic concepts of fixed-point number representation.  I also... read more >>

Introduction to Model Advisor 6

Posted by Seth Popinchalk,

How do you check your model for common mistakes?  Do you have an easy way to verify that your model matches the MAAB (MathWorks Automotive Advisory Board) Control Algorithm Modeling Guidelines?  In this post, I will introduce model advisor and show you how easy it is to use automated checking in your modeling process.... read more >>

Challenge: Metronome and Cart Equations of Motion 6

Posted by Seth Popinchalk,

I haven’t
seen much activity on the Metronome Synchronization Challenge, so I want to provide a peak at the basis
for my solution.  I took the approach of modeling a pendulum, and then linking
its dynamics to the dynamics of a cart.  The challenge is choosing the right
coordinate systems to assign to each... read more >>
