ANTENNA-MATCHING-DEVICE-BASED INFORMATION AND CONTROL SYSTEM WITH CENTERED TUNING ELEMENTS

Abstract

Background. Ensuring the stability of information and control systems in the transition mode by antenna matching devices, which are multi-connected control objects, is a difficult task. It is necessary to conduct research on the choice of the matching device type, the synthesis of the meters and sensors used the places where they are connected, and the development of a control algorithm that ensures the system’s stability. The purpose of the research is to ensure the stability of the control system by developing an algorithm with Autonomous (separate) control of configuration elements. Materials and methods. The antenna-matching-device-based information and control system with centered tuning elements is an object of research. The subject of research is the control algorithm and its mathematical support. The method of circular diagrams of resistances and conductivities in a Cartesian coordinate system from the theory of functions of complex variables and the method of studying functions on an extremum from mathematical analysis are used. Results. Developed algorithm and software of information control system of the discrete antenna-matching unit with the centered parameters of the tuning elements, ensuring stability of the whole control system through autonomy settings for individual elements. Conclusions. The mathematical expression needed for design and operation of antenna-matching-device-based information and control system, to determine based on the values of the coefficient of a traveling wave in the antenna feeder, the current, minimum and maximum values of the tuning elements of the matching device at the operating frequency of the radio station.
