Research On Flight Control And Simulation Technology Of Unmanned Gyroplane

A certain type of unmanned gyroplane is taken as an example for research. The modeling andautomatic flight control technology are studied.Firstly, the differences of rotors characteristics between gyroplane and helicopter are analysed.Rotating characteristics in vertical descent and forward flight are also analysed.While modeling, thegyroplane is divided into three parts. They are longitudinal manipulate corresponce parts, transversemanipulate corresponce parts and push equipment parts. Each part’s simplified model is establishedrespectively. The three parts are combined into the simplified model of gyroplane. The handling isanalysed.Secondly, the attitude loops of pitch and roll are designed. Based on these, the design of velocityloop and height loop is carried out. According to the turning fight characteristics of the gyroplane, theturning flight close-loop based on deviation modification is designed. Taking into account of thenon-optimal parameters, a optimization algorithm called differential evolution is used to optimizeparameters. Simulation results show that the gyroplane’s performance meets the performancerequirements and the proposed control methods are feasible and effective.Finally, the implementation scheme of unmanned gyroplane control system is described. Itmainly contains the implementation of hardware and software. The implementation scheme ofhardware-in-the-loop simulation is designed. The hardware-in-the-loop simulation results show thecontrol strategy and control method are effective.In this paper, the simplified model of gyroplane is established. The flight control strategy isdesigned and proves its accuracy by simulation results. These efforts establish the theoretical andengineering foundation for fully autonomous flight of gyroplane.
