Abstract:

The electro-hydraulic force servo system was introduced, which was used to give force to a certain kind of airplane during its experiments on the ground.The characteristics and structure of this electro-hydraulic force servo system was analyzed in detail. The control strategy of the system was emphasized on, and the experimental results of stop mode, normal mode and back mode were also given respectively. The experimental results show that the dynamic trace error of this electro-hydraulic force servo system is less than 15%. This is suitable to engineering applications.

Key words: airplane, simulation on the ground, thrust in reverse, electro-hydraulic force servo system, dynamic force track error
