Control of speed and starting current of turbojet using methods fuzzy and sliding in the presence of uncertainty

The purpose of the article is control of speed and starting current of a turbojet engine on the first step starting electrical. The controllers are designed to reduced peak of starting current to the minimum possible value. In this paper, special attention was devoted to engine speed during reducing starting current. So that reducing starting current is done by sliding control and fuzzy controller used for control startup speed. Fuzzy controller is responsible for regulating the coefficient of sliding controller but so that the speed at end of the first stage be not less than 1818rpm. Finally, reducing of current compared with no control and will observe dramatic reduction of starting current.
