Buryk M. Cascade control systems coordinates of electric drives based on the concept of inverse problems of dynamics

Object of research - process control electric drives of cascade structure; purpose of research - development of control methods based on the concept of inverse problem of dynamics combined with the minimization of the local instantaneous energy values functional for improvement the quality of control electric drives cascade structure in conditions coordinate and parametric perturbations; methods and techniques - in solving the tasks of the thesis applied methods of the theory of electric drives and automatic control theory, including development of robust methods of control laws based on the concept of the inverse problem of dynamics combined with the minimization of the local instantaneous energy values functional, laws control research carried out by means modeling and on of physical the experimental installations; theoretical and practical results - was further developed the principle control of coordinates electric drives in cascade control systems through the use of instantaneous value of the magnetic field energy while minimizing local functionals in the inverse problems of dynamics, providing robust control systems currents and flux linkage to a change in the parameters of electric motors; obtained the method of calculation algorithms control of electric drives AC and DC , which provide high dynamic control accuracy and robustness to the uncertainties caused by the influence of parametric and coordinate perturbations.
