LARGE GAIN METHOD IN THE PROBLEM OF SELF-ORGANIZATION OF CONTROL SYSTEMS OF STRUCTURALLY INDETERMINATE LINEAR PLANTS WITH SWITCHES. I

A method of constructing self-organizing tracking systems in the class of minimally phase linear plants operating under conditions of a priori uncertainty and structural switching is considered for the case when the main control circuit has a large gain coefficient. It is assumed that at an arbitrary point of time, the numerator and denominator of the plant transfer function can change by a jump within the previously known boundaries of their permissible values. To solve the problem of synthesizing a self-organizing plant control system with a relative degree greater than one, a dynamic corrector is used in the main contour of the system.

Nonlinear-periodic control system for non-affine multi-connected plant with state delay

The article deals with the synthesis problem of control system regulator for non-affine multivariable dynamic plant with state delay. The plant operates in periodic modes and also in the presence of external disturbances and parametric uncertainty. As a solution methods the hyperstability criterion, the fast-acting dynamic corrector, and L-dissipativity conditions are used. The key step of the system synthesis is the receipt for V. M. Popov’s integral inequality special estimates that ensure the fulfillment of the control goals. In final article part with the help of simulation the dynamic processes taking place in the proposed control system, are visually illustrated.
