Development of Fast and Soft Landing System for Quadcopter Drone using Fuzzy Logic Technology

The popularity of Drones, also known as unmanned aerial vehicles (UAVs), are highly increasing in various fields because of its multi-skilled performance and operational flexibility. Landing of the drone is the most difficult part of a flight. Literature review reveals, there are many kinds of landing controllers are available for drones but those controllers take more time for landing a drone. In this paper, we developed a fast as well as a soft landing control system for quadcopter drone using fuzzy logic technology. More specifically, we designed a fuzzy logic based controller in MATLAB/Simulink and implemented it to Raspberry pi. The Raspberry pi is connected with an ultrasonic sensor for altitude calculation. Here we used Pixhawk as the main flight controller, and the Pixhawk receives the real-time landing control commands from the Raspberry pi. Several landing tests were conducted using the designed fuzzy landing control system, and the flight test data shows that the quadcopter landed softly with minimum time than the other existing landing control technologies.
