Description
  • Pomocí metody časově posunutých dat jsme zrekonstruovali dynamiku plasmatronu. Pro různé hodnoty vstupního proudu a různé hodnoty průtoku argonu jsme následně tuto dynamiku porovnávali. Pomocí fotodiod byl ze 4 směrů opticky porovnán elektrický oblouk uvnitř plasmatronu i výsledný proud plazmatu. Napětí a proud oblouku byly zaznamenávány synchronně a s těmito záznamy vyzařování proudu plazmatu. Rekonstrukce dynamiky pomocí metody časově posunutých dat, jak ze záznamů proudu tak ze záznamů optických, byla použita k další analýze. Výsledky ukazují, že měnící se charakter výsledných fázových portrétů má vztah ke stabilitě pracovních podmínek, které se projevují například změnami polohy osy proudu plazmatu. (cs)
  • Method of time-embeddings is used for reconstruction of plasma torch dynamics. Different input currents and argon flow rates have been used and the resulting dynamics of plasma flow compared. Electric arc inside the plasma torch and generated plasma jet were observed optically by arrays of photodiodes from 4 directions. Arc voltage and current were recorded simultaneously with the optical radiation. Reconstruction of process dynamics from both the records of arc current and plasma radiation by the method of time-embeddings was used to analyze the data. The results show that the changing character of the resulting phase portraits is related to stability of working conditions reflected by the changes of the plasma jet axis position.
