Optimization of a disturbance-invariant automatic control system

The possibility of optimizing the automatic control system invariant to perturbations by expanding the structure of the perturbation control coefficient is shown. The use of the algebraic-integral-differential structure and their individual components is analyzed, and the prevailing influence of each of them on the speed of operation, the nature of the system's behavior, and its fixed error is established. Numerical modeling confirmed the effectiveness of using such a structure of the controller for the impact of disturbances to ensure speed and quality of control under arbitrary external disturbances.
