| Abstract: | Aiming at evident shortage of dynamic inversion controller of UAV,dynamic inversion controller based on NN is designed through online NN compensating inversion error.A single hidden layer NN structure is constructed and the stability of the whole closed loop system is proved.Also the stable adjustment arithmetic of online NN weight is proposed.The robustness,the adaptability to fault and the response capability to actor delay time of the scheme are verified by simulation.It is also proved that the online NN... |
