Bosak A. Electric positional drive control with non-autonomous defining model and fuzzy regulators

Dissertation is devoted to the development of new methods of reproduction with the lowest error of control variables defining positional effects of electric drive.Dissertation solves a scientific problem of quality increasing positional drive control complex structure with distributed parameters, influenced by external and parametric effects, through the development of a control method based on the use of non-autonomous defining model and the application of fuzzy controllers. The developed control algorithms provide low sensitivity to changes in the electric drive parameters. The fuzzy controller structure is formalized, based on the use of its adaptive properties for a given positioning accuracy under varying parameters and load, which ensures low sensitivity control system to parametric perturbations. On the basis of the proposed methods synthesized and investigated algorithms compensate for disturbances in the control object, based on the use of special compensating model, functioning according to the inverse dynamic algorithm for the actual speed or position using fuzzy controller, ensuring stabilization of the dynamic control of quality indicators during the term of the parametric perturbations. Keywords: positional drive control, fuzzy controller, defining model, the system subordinate regulation.
