Abstract

At the present time, phase auto-adjustment systems are widely used, in which frequency stabilization and frequency tracking is achieved due to phasing of the reference (setting) and control voltages. Frequency auto-adjustment systems solve this problem as a result of direct measurement of the difference in frequencies of the reference and control voltages, and reduction of this difference. The scientific task solved in the research is to increase the dynamic characteristics of automatic tuning systems, to increase the dynamic accuracy and speed of frequency auto-tuning systems of radio monitoring devices with astatism. Therefore, the object of research is the system of automatic self-adjustment of military radio monitoring equipment. The subject of the research is the dynamic, root mean square errors of automatic self-tuning systems under different laws of change of the disturbing influence (input signal frequency deviation) and the speed of the systems. The methods of analysis and synthesis, the theory of complex technical systems and the theory of radio receiving devices were chosen as the basic mathematical apparatus in the proposed research. The research proposed a combined system of frequency auto-adjustment of radio monitoring devices with astatism, as well as basic mathematical expressions that describe its operation. In the process of research the following tasks were solved:

– an analysis of the dynamic characteristics of a static system of frequency auto-adjustment with the principle of deviation control was performed;

– a functional scheme and a mathematical model of a combined frequency auto-adjustment system with first-order astatism and increased speed were developed.

One of the important advantages of the proposed mathematical model is the increased efficiency of frequency tuning depending on the type of signal compared to known frequency autotuning. This is accepted not only in the case of changes in the disturbing influence according to deterministic laws, but also in the case of random disturbing influence.

The direction of further research should be considered the increase in dynamic accuracy (reduction of dynamic, root mean square errors) and speed of frequency auto-adjustment systems.
