FADEC/EEC Control Law Design

Does anyone know of any good books detailing turbofan FADEC control law design?
I've looked into quite a few gas turbine and jet propulsion books, but while they can be very detailed with regard to the turbo-machinery they all seem to lack detailed information on electronic engine control.

Thanks
Obi

Their was a paper discussing the Z notational form in the specification of the 744 RR FADEC... I read it at University sad git that I am. I think it may have been published by the Computing Unit (Oxford Uni). I will try and find it for you.

The Spec obviously should encompass the design.

The engine manufacturers provide the books free of charge to their customers who take their maintenance course. probably can find one on E-Bay. I've got one someplace but it ain't handy right now.

This is quite surprising. The Control Laws themselves are proprietary and I would have thought would be closely guarded by the companies that own them, as well as most other data that reside in the 'black' boxes. I am looking for as much detail as possible even from general sources, nothing specific to an engine type. If however this info is available (engine specific) and isn't a problem, I would appreciate it.

Thanks
Obi

Ah I was too general in my read and missed the word "law"

I was relating only to a mechanics understanding.

No problem lomapaseo, I'm sure the maintenance pubs make for interesting reading.
