Kevin, in my experience in the aerospace industry, we had a whole separate group of controls engineers. Then, the software engineers took the equations and algorithms and turned them into very compact code. The later was necessary because the processors were not very powerful. I got into it just as digital control systems were coming into their own. The previous systems were analog. Fast, but hard to program and tune.
Now, we can get processors, inquantity, that cost $50 to $1. Many have built in FFT instrustions. They also have built in A/D and D/A. It is a brave new world.
As an industry, we now need to up our game and provide contractors with easier ways to properly identify and report counterfeit products and build collaboration between manufacturers, design engineers, industry organizations, and government.
The shift to aluminum is gaining momentum and the demand from automakers for aluminum is soaring, "expecting to reach one billion pounds this year, up from 200 million in 2012, and to grow by more than 30% annually through 2020."
