Flight Control And Realization Of Unmanned Rotorcraft

Rotorcraft is a kind of aircraft with rotary-wings providing lift,which has the characteristics of flying vertical take-off and landing,hovering,etc.,and is widely used in military and civil applications.In this paper a new configuration of unmanned rotorcraft as the research object,in order to realize autonomous flight,according to the existing relevant practical experience,combining the theory of flight mechanics,automatic control,computer technology and other related disciplines,design the rotorcraft flight control system.In this paper,a new design scheme for unmanned rotorcraft is proposed based on the research of unmanned rotorcraft.Besides,analysis of the flight principle and structure of the rotorcraft and carry out the analysis of force and torque,establishing the mathematical model of the rotorcraft.In combination with the twelfth state equation,analyze the coupling analysis and stability of this kind of rotorcraft,and describe its control difficulties.A flight control strategy for a new type of unmanned rotorcraft is presented,and the autonomous navigation control loop is designed,including the high control loop,speed control loop and attitude control loop.The software and hardware design of the flight control system for unmanned rotorcraft are designed to realize autonomous flight.Finally,combining the mathematical model and control strategy,the simulation software of the rotor is compiled to verify the effectiveness of the control strategy.After the simulation of several subjects,the proposed control strategy can realize the autonomous flight of the unmanned rotorcraft.
