The dissertation analyzes two-mass electromechanical systems, computer simulation models are formed. Study uncontrolled and controlled two-mass electromechanical systems by applying different controll methods. Experimental stand design of two mass electromechanical system are described. Presented results of the transion responses.
The thesis layout consists of introduction chapter, four main chapters, conclusions and bibliography chapter.
The introduction reveals the investigated problem, importance of the work and the object of research as well as describes the purpose and tasks of the paper, research methodology, scientific novelty, the practical significance of results examined in the paper and defended statements. The introduction ends in presenting the author’s publications on the subject of the defended dissertation, offering the material of made presentations in conferences and defining the structure of the dissertation.
The first chapter revises used literature. The reduced one-mass system and elastic system with clearance mathematical description are presented. Mathematical models of induction motors in different coordinate system are presented. Describe the vector and fuzzy logic contloll method. At the end of the chapter, conclusions are drawn and the tasks for the dissertation are reconsidered.
In the second chapter formed simulation models of induction motor, model of two-mass system with the theoretical expression in time of induction motor torque. Simulation models of vector control and fuzzy logic controller are presented. At the end of the chapter, conclusions are drawn.
In the third chapter compose two-mass electromechanical system models with induction motors models, with vector control and fuzzy logic controller models. Simulation test by changing the system parameters and load are carried out. Transion responses of speed and torque are presented. At the end of the chapter, conclusions are drawn.
The fourth chapter describes the experimental stand design, special speed measuring device creation. Described studies with defferent loads, step responses of speed and torque are presented. Comparing the experimental and simulation results, the adequacy of simulation results are verification.
The results of the work were presented in nine scientific articles: two articles published in journals quoted in Thomson Reuters Web of Science databases, four articles in referred international conference materials and three in other conference materials. Nine reports were presented on the subject in conferences at national and international level.
