| description | The paper deals with a control system for nonlinear dynamic processes in a buck converter based on the target-oriented control and belonging to the class of discrete automatic control systems. The main task of the proposed system is to stabilize the desired dynamic mode, which provides a minimum amplitude of output voltage fluctuation. The author proposes a hardware-software calculation method of the fixed point coordinates in the desired periodic mode, when the average values of state variables are determined by hardware using low-frequency filters, and the fluctuation amplitude of the output physical quantity in the desired dynamic mode is estimated on the basis of analytical expressions. Computer simulation of the proposed system is performed and its efficiency is shown. The proposed approach to estimating the coordinates of the fixed point of the desired mode in real time can be applied to a wide class of DC/DC converters. |
