Andreyeva N. Synthesis of electrodrive systems with two-zone optimal relay control system

3. Object of study are processes of optimum management direct current electrodrive with two-zone regulation of velocity. Purpose of studies - an improvement of relay-typemanagerial electrodrive systems, most further their development for governing two-mass and two-zone elec-trodrive systems by development of algorithms and system structures of relay-type governing velocity of engine with independent by excitement. As methods of study were used general methods of theory of autocontrol and special methods of theory of optimum management (analytical con-structing regulators on base of dynamic programming), as well as methods of mathematical modeling and functions of sensitivity. Checking the main theoretical positions was executed with using numerical modeling in the ambience SIMULINK package MATLAB. For the first time installed dependency between the frequency of slitherring mode of relay-type regulator of the most internal sidebar, constant time of the filter of at the input thyristo r converter with phase management and possible asymmetry of its controlling pulses; for the first time received dependencies of frequency of slitherring mode of internal sidebar an electrodrive from the gain factor, inertia, areas unsensitivity real operation amplifiers; for one-mass and two-mass electrodrive systems with two-zone regulation of velocity for the first time synthesized governing the relay-type regulators, allowing optimum perfect given motion paths; The results of the thesis work is sent to the Alchevsk metallurgical combine for using at modernizations an elec-trodrives of rolling shops , are used in the scholastic process a Donbass minning and metallurgical institute when studying a special course of theories electrodrive and managerial systems for the profession 7.092203.
