In this final project is described, modeled and researched vector controlled electric drive with Fuzzy and PI controllers. In the introduction is discussed importance of controlling electric drives, presented advantages of induction drives against DC drives, presented this work content. In the Theoretical part first of all is presented scalar control methods, described implementation schemes. After coordinates transformation and them mathematical expressions presentation is explaining principle of vector control. After that is reviewed direct and indirect vector control methods, flux determining methods, used in direct vector. Also in this part is shortly described direct torque and fulx control method. Finally is reviewed Fuzzy logic and controllers, employment in induction drives. In the exploratory part is created mathematical model of induction motor. After that is composed indirect vector controlled induction drive computer model, described its elements and working. With created model is executed tests with drive working on uncontrolled or controlled mode when using Fuzzy or PI controller in speed control link. In this part is laid and described results of simulations. Conclusions and recommendations are presented on the part the summarized results of the research. Structure: Introduction, summarize of the literature, purposes and tasks of research, Theoretical part, The exploratory part, Summarize of research results, Literature and others sources. Thesis consists – 78 p. text, 53 pictures, 4 tables, 36 bibliographical entries, 2 web pages access.
