Ranking of factors influencing the functional reliability of a quadcopter and improving its automatic control system

Abstract

The article presents the results of the study of internal and external factors influencing the reliability of a quadcopter.
 The aim of the research was to develop a ranking method of internal and external factors affecting the reliability of the quadcopter, and to rank them according to the developed method, which takes into account the main sources of failures and influences on the reliability of its automatic control system, and on their basis to develop a rational algorithm of quadcopter’s automatic control system.
 In the developed ranking method, the value of the statistical estimation of the probability of failure-free operation of each quadcopter component was selected as a ranking criterion.
 In the analysis of the reliability of the quadcopter, structural methods of calculating the reliability were chosen, because they give more unbundling into elements and blocks, which is important for finding the characteristics of reliability. The article presents the calculations of reliability indicators for each element, unit and the entire UAV, developed a structural and logical scheme of reliability of the quadcopter.
 According to the developed ranking method, the algorithm of operation of the quadcopter automatic control system is designed, which does not exceed the main restrictions associated with the operation of the quadcopter in general, with proper operation of elements, units, systems and equipment, which increases the reliability of automatic control system and UAV in general.
