Situational control methodology in control of aircraft turbo-compressor engines

Aircrafts' turbo-compressor engines may be considered as very complex systems with many mutual and also positive feedbacks. Another characteristic of such systems is that they operate in a very large range of outer environment parameters which causes very different behaviour within their working conditions. Critical susceptibility to erroneous states where requirements for reliability are set to highest degree, it is necessary to secure control of such engines in their every state and secure their operation under every environmental or engine conditions. Situational control methods offer such tools to secure not just stabilization of an engine, but its control, using different control strategies for different working conditions.
