Abstract: The application middle ware of flight control software is developed,to implement the dynamic change of control architecture and the dynamic reconfiguration of control components.Based on model inversion technology,the rotation inversion and translation inversion controllers under some condition are designed,and inversion errors under other conditions are compensated by the on line neural network.The example simulation results demonstrate that the method of the open platform combined with neural network can implement the autonomous flight of unmanned helicopter and is of great value both in theory and in engineering application.
