- Abstract
Variable structure control systems (VSCS) refer to automatic control systems operating in "special modes". These systems do not use adaptation algorithms. However, they have robust properties against some uncertainties. At present, the robust characteristics of VSPS have not been sufficiently studied. In this paper, new control algorithms have been developed to control dynamic objects with parametric and signal uncertainty. These algorithms operate in a sliding mode, implemented in systems with a variable structure. The structure of a robust regulator consists of relays with different static characteristics: a two-position relay without hysteresis; to reduce the switching frequency, a relay-linear regulator with a linearity zone. This design allows the system to be stabilized in a small vicinity of the equilibrium position without the occurrence of self-oscillations. As a result of simulation modeling on Matlab/Simulink under conditions of parametric uncertainty, dynamic characteristics were obtained that confirm the increase in robust indicators relative to known systems.
