In the final dissertation you will find analyzed the two - mass electromechanical system, finite tightness shaft and non-linear mechanical link included. Explored system shaft has finite tightness, non-linear element - backlash between the parts of mechanical link. The researches of two - mass electromechanical system were made using Simulink program pack. In this paper I have made the structural system scheme, transmission functions and simulated process of two - mass dynamical system. Gained motor and outlet shaft angular rotation speed and motor's electromagnetic moment transitive process curves, by all tightness and backlash worth' s. Researched results give new information about the two - mass electromechanical system' s dynamical process.

Šiame baigiamajame darbe išnagrinėti tiesiaeigio asinchroninio variklio ypatumai ir naudojimo sritys, padaryta dažnio keitiklių ir juose naudojamų valdymo būdų apžvalga. Išanalizuoti impulsų pločio moduliacijos realizavimo principai, apžvelgti skaliarinio ir vektorinio valdymo metodai. Remiantis išanalizuota teorija sudarytas tiesiaeigio asinchroninio variklio matematinis ir kompiuterinis modelis α-β ir x-y koordinačių sistemoje, sudaryti TAV dažninių atviros ir uždaros sistemų matematiniai bei kompiuteriniai modeliai. Sudarius atviros ir uždaros sistemos modelius: gautos TAV antrinio elemento linijinio greičio, kelio ir jėgos pereinamųjų procesų charakteristikos ir palyginti rezultatai. / The properties of linear induction motor and areas of its application are analyzed; frequency converters and their control methods are discussed in this final work. Methods to realize a pulse width modulation are analyzed, scalar and vector control principles are discussed. The principle of operation of control systems applied in frequency converters is analyzed On the base of analysis mathematical and Simulink model of linear induction motor in α-β and x-y reference frame is developed, mathematical and Simulink models of frequency variable open and closed systems are carried out. Open and closed systems are investigated: transient characteristics of secondary element linear speed, developed force and way are analyzed and results of different characteristics are compared.
