UAV Flight Safety System Based on Fuzzy Logic

Abstract

The article proposes a method of deciding on the continuation or termination of the UAV flight on the basis of fuzzy logic to ensure its trouble-free flight, which will be used in the future to build an onboard monitoring system of the power supply of the unmanned aerial vehicle. The developed method of decision-making allows to determine the residual battery life on the basis of data on current voltage, battery temperature, temperature on board the UAV and the direction and strength of the wind, using which the computer system will make recommendations for continuing or terminating the UAV flight task. The method of decision-making using fuzzy logic involves the formation of linguistic variables, which are the input information parameters and the output decision, their linguistic terms and membership functions, as well as a system of rules for decision-making. The voltage at the output of the battery, its surface temperature and the wind direction on board the UAV were used as input variables, and the residual battery life was used as the output linguistic variable.

Practical applications of fuzzy set theory in flight safety management

“…Of the recent works on flight safety, which actually use the methods of FST, it is appropriate to note the articles related to the current topic of the safety of unmanned aircraft systems (UAS). The article [14] presents a method that solves the problem of monitoring the state of power supply. The method allows you to use fuzzy logic based on the current voltage, battery temperature, wind parameters to determine the remaining battery life and automatically adjust the flight plan.…”
