Simulation modeling of robust control system for nonlinear non-affine objects

Abstract

The article deals with the simulation of robust control system for nonlinear non-affine scalar dynamic objects. The considered system is constructed by using the hyperstability criterion, dynamic filter-corrector and the L-dissipativity conditions. This approach enabled synthesis of the robust law that provides fulfillment of specified quality indicators of the system operation in the presence of nonlinear parameters and structural disturbances. The aim of this article is the study of dynamic characteristics of the robust control system for non-affine nonlinear control objects with different nonlinear parameters. With help of computational experiment, the regulator coefficients are selected, which provide a predetermined precision tracking of the command signal.
