The Journal of European Physics Plus, which is one of the journals of the international publishing  (Sprinker) and classified within the Clarivet (impact factor = 3.228), a research by Professor Dr. Fadhil Rahma Taher, professor at the College of Engineering at the University of Basrah with postgraduate student Ahmed Sadiq Hanish, entitled (Fission and Chaos in a Controlled Induction Motor System indirectly)

Control parameters change system. The slip velocity compensator, integration gain (K_iw) and proportionality gain (K_pw) for the velocity loop controller were used from the system dynamics. The effects of changing the integration gain (K_iw) and the proportionality gain (K_pw) on the system dynamics were investigated. Also, the system exhibits a cycle-doubling fission of cycles (cycle-2, cycle-4, cycle-8, cycle-16) leading to chaos.
