Automatic control systems: optimization and sensitivity study

Abstract

Abstract The paper discusses the optimization of a pulsed automatic control system (ACS) with constant parameters, which is used to control non-stationary objects. We obtained the dependences of the integral quality criterion on perturbations acting on the control object. The sensitivity of the ACS was studied by simulation using MATLAB / Simulink. The system was optimized based on the criterion constructed taking into account sensitivity to parameter variations. It is shown that the synthesis of the ACS insensitive to changes in characteristics is advisable only if the deviations of the parameters are small. In this case, the quality of automatic control will improve.
