Pryashnikova P. Construction of stability and quality regions of automatic control systems with delays

Subject of inquiry is automatic control systems with delays. Purpose of work is increase the effectiveness of designing of automatic control systems with delays. In a thesis an offered algebraization of construction of stability and quality regions of automatic control systems with several delays on the basis of a common method of construction of the equations of boundaries of required areas. The equations of boundaries of stability regions, stability margins, index of variability, pass band, guaranteed overshoot and guaranteed lack of an overshoot in a canonical form are obtained. Canonical the equations are, for which one in a thesis the special method of a solution is designed. The program complex RegCAD of construction of stability and quality regions in space of parameters of automatic control systems with delays is designed. With the help of methods offered in a thesis, and designed software, parametric analysis stability and qualities of an automatic control system by heavy fuel viscosity of ismade, which one includes two delays links. Offered theoretical methods introduces in studies in Sevastopol national technical university. Results of thesis may be used to the energy and radio engineering manufacturing firm.
