Thank you very much ChristiaanJ ; this Concorde AFCS circuit board (analog control law computing board) is very beautiful; like the Concorde is ! How beautiful it was in the sky !
effectively what I still want is ...
- a full CMM (component maintenance manual),
- a full system block diagram,
Despite digital systems overcame on analog system, I am sure that the latter are the best to modelize and control non-linear unstable circuits.
Digitalizing brings many problems at the same time it seemed anything became easy by linearisation, and matrix computing.
Future is ahead !
