Is it Possible to Use the Experimental Identification Based on the Transition Characteristics for Micro Turbo Compressor Engines?

摘要

Experimental identification as one of the possibilities of creating mathematical models of complex systems is a fast, simple and easy-to-use methodology. Even with a low percentage of knowledge of the modelled object (functionality, internal bonds, etc.) it is possible to obtain a mathematical model with high quality - similarity - verification. The disadvantage of experimental identification is the necessary existence of a functional complex system and a measuring - sensing apparatus. The Laboratory of intelligent control systems of aircraft engines has four full-featured functional systems - small and micro turbo compressor aviation jet engines. Experimental identification of small jet engines based on the measured transition characteristic is being researched using these engines. The question and topic of this article is to verify the possibilities and ways of creating mathematical models by experimental identification based on the acquired - measured transition characteristics for the smallest category of aircraft engines - micro turbo-compressor jet engine and evaluate obtained simulation models of different complexity.
