Re: to build a reliable machine
So the control system theory we learned is applicable to real life.....except few are willing to pay for it whereas many are trying to digitize it.  I like a good old analog control loop with a Bode plot like Lloyd Dixon used to write about.

to build a reliable machine
except a turbine itself you should keep in mind a huge amount of minor details, that seem to be negligible, but might cause big troubles.

My own turbine was destroyed when the anemometer impeller was blown into small parts. The controller was confused by receiving wrong data and set the startup angle and load. Last wind speed registered was 35m/s...

Blade Angle Control
The angle of the blades is changed according to the apparent wind speed at the blades.

The wind speed varies with height as the square of the height (parabolic function).  When the blade is pointing to the ground, the wind speed will be minimum.  When pointing straight up it will be maximum.  Is the angle of each blade changed individually for this wind speed variation with height throughout each rotation?

Of all the components that go into a circuit, magnetics seem to have the most complexity in terms of several factors including construction, parasitics, linearity, and variations.
Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the emergence of solid state electronics as well as the phasing out of mechanical components in favor of electrical components.
It’s been a while since I addressed Bode plots as a main subject so I thought this would be a good opportunity for a refresher on a very basic stability tool
Although they are a simple device, diodes do have a number of traits to consider. These traits are often application dependent.
