Elaboration of an almost optimal system by means of an electronic analog

The paper deals with design of an almost optimal control element, as to its highspeed, for an electronic actuator of a press device in a rolling mill. The design method consists in division of the known part of the system into blocks.
A simple optimal control element is elaborated for each block; input value of blocks is controlled in such a way that difference between a real input value and an optimal one approaches zero.
The system in question was tested by means of an electronic analog. The system was proved to shorten (2–2.5 times) control time as compared with a linear control system.
