A graph analysis method for calculation of dynamic responses of electromagnetic mechanisms in optimal control

A graph analysis method for calculation of dynamic response of electromagnetic mechanism is studied which makes use of direct graph analytical integration of the initial equations and the method of memorizing the «backward», according to A. A. Feldbaum, motion. A solution s given for mono- and bipolar laws of optimal control and for control with forcing. An example of calculating a d.c. power electric magnet in optimal control and in control with forcing.
