This research proposes a robust nonlinear hybrid control approach to the speed of multi-input-and-multi-output separately excited DC motor (SEDCM). The that was under consideration experienced parametric uncertainties and load disturbances in weak field region. proposed technique aims merge benefits adaptive backstepping (AB) integral sliding mode (ISMC) enhance overall system’s robustness. unk...

The dependence of continuous mappings on a certain number coordinates was intensively studied in the works many mathematicians middle 20th century. It has become convenient tool study properties mappings. most general results this direction were obtained [5], where necessary and sufficient conditions for functions products from obtained. Starting with [8] separately became subject research at C...
