Methods for design of electromagnetic d.c. drive control units

In the framework of problems in design of optimal control for an electromagnetic d.c. drive the paper discusses methods for design of optimal control units for a d.c. electromagnetic drive, specifics of using two- and three-interval control laws for neutral and polarized electromagnetic units. Structural diagrams are described for optimal single- and bipolar control of an electromagnetic d.c. drive control are given; versions of designing these structural diagrams are analyzed.
