The process of forming a “knowledge base” of a fuzzy controller is considered. The results of mathematical modeling of the longitudinal UAV control channel with a PID-controller and a fuzzy controller in the control loop are presented.enUnmanned Aerial Vehicle (UAV)Fuzzy controllerLongitudinal control channelPilot-navigation complexHeight stabilizationAutomatic control systemArticle10.14313/JAMRIS/3-2020/26
