On strongly nonlinear phenomena in electrical machines

The paper deals with some general aspects of strongly nonlinear real-world systems which behavior can be adequately described by means of finite number of internal interactions. New concept of abstract state space energy has been introduced and developed as a tool for strongly nonlinear system analysis, synthesis and design. The basic idea is motivated by real-world experiments inspired by dynamo effect as mechanism of the Earth's geomagnetic field generation including its chaotic reversals. Theoretical concepts are illustrated by real data gained from a simple AC power system and tested by simulation including that of chaotic phenomena.
