Closed Loop System

The concept of DODF and other two evaluation indices based on DODF were proposed. Based on the optimal preview acceleration driver model, the effect of driver model parameters on the performance of driver-vehicle-road closed-loop system was studied by the closed-loop system simulation. The results show that the preview time of a driver who has good driving habits should be always larger than a certain valueTP0, the increase of both nerve delay timetdand muscle lag timeThlead to the increase ofTP0, andtdhas more effect onTP0thanThdoes. The increase of bothtdandThlead to the decrease of DODF, andtdhas more effect on DODF thanThdoes. Furthermore, the increase of bothtdandThalso lead to the increase of both tracking indexJEMand driving load indexTCM,tdhas more effect onJEMthanThdoes, andThhas more effect onTCMthantddoes.

The Stability

The paper proposes a method to design AANN dynamic inversion controller through online ANN compensating inversion error. It mainly aims at evident shortage of dynamic inversion controller of UAV. A single hidden layer ANN structure is constructed and the stability of the whole closed loop system is proved. Also the stable adjustment arithmetic of online ANN weight is proposed. The robustness, the adaptability to fault and the response capability to actuator delay time of the scheme are verified by simulation. It is also proved that the online ANN has improved the performance of dynamic inversion controller well. It has important reference value for designing advanced flight control systems of UAV.
