OPTIMIZATION OF TRANSIENT IN SYSTEM WITH ELECTRIC AND HYDRAULIC CAPACITY AT PRESENCE OF SOURCE ENERGY LOSSES AND INDIRECT LOSSES OF POWER MEDIUM

Abstract

A decision over of task of optimal control on a criterion a consumable energy minimum is
brought by the real voltage source, which works in a chain with parallel connection of ideal capacity and direct-current source. The comparative analysis of optimal and optimized step control law is executed by such
system. Analogical problem is set the and decided for the hydraulic system taking into account pipeline resistance and indirect cost of liquid on the minimum energy consumption criterion in the process of hydraulic
capacity filling. The conclusion of analytical expressions is given, allowing to expect basic indexes systems
of optimal and step control. The laws of optimal and step control are confronted by the electric and hydraulic
system. The results of calculations are convinced of that the hydraulic system other things being equal assumes the large economy of energy due to an optimal control as compared to the variant of the optimized
step adjusting, what electric. It is constrained with that functional, investigated on an extremum, in case of
the hydraulic system depends on the cube of the productivity index is serve, and in case of the electric system - from the square of analogical index, which a current is.
