Research On Flight Control And Visual Simulation System For Unmanned Helicopters

Unmanned helicopter combines the advantages of unmanned aerial vehicles and helicopters,which has important significance both in the field of civilian or defense. Unmanned helicopter flightpath control is the primary goal of complete autonomous flight. In order to solve the optimization andvisual simulation of the flight path of the unmanned helicopter, developing a multi-channel visualsimulation platform for unmanned helicopter control system.Firstly, according to the theory of classical control method, designed the corresponding flighttrajectory control system for the three links of unmanned helicopter. Verify the performance of thiscontrol system on real-time trajectory simulation. On this basis, introduce the particle swarmoptimization. The performance advantage of the new algorithm is proved through the comparison ofimproved particle swarm optimization and the original algorithm. Compare the performance of thenew algorithm control parameters with the original control parameters for the unmanned helicopterflight attitude control.Secondly, based on the established unmanned helicopter flight control system, realize the datalink of Matlab simulation software with FlightGear3D flight simulation software. And configuredcoordinates between the virtual simulation environment, unmanned helicopter model and space scenesand other elements, to achieve visual simulation of virtual environments authenticity. Designed ofman-machine interface, able to complete the setup simulation environment and operating parameters,monitoring the simulation is running, receiving user input commands and other functions.Finally, in order to increase the realism of the visual simulation designed the multi-channeldisplay technology on the basis of FlightGear visual simulation system. For the desired performanceanalysis to complete the design of the structures of the entire platform hardware systems and softwareprocesses. Realize the multi-machine communication and video multi-channel processing based onFlightGear software. By two unmanned helicopter flight modal presentation, to show vividdemonstration of the effect of the entire flight simulation process in the wide viewing angle of the bigscreen to the observer.In this article, has completed design of an unmanned helicopter flight control system, a completeset of flying multi-channel visual simulation platform is built on this basis. Make the simulation databe three-dimensional, in the most direct visual experience. Through this multi-channel visualsimulation system can better analysis unmanned helicopter flight control, combined simulation, demonstration and validation of the three aspects into one.
