It is a good article however I would disagree that the traditional approach would start with solving the ODE.  We normally start using an Laplace transform and writing the transfer funtion.  From this, the poles of the system can be identified and any significant problems identified before spending the time to create a complex model. 

I would recommend never skipping the back of the envelope analysis.  It is very valuble to use it check that your model is locked in.

Excellent article. HIL testing just makes all kinds of sense, and the Rover example illustrates how the modeling environment can be used for other purposes. Thanks.

The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
