QFT robust control of direct drive electro-hydraulic servo rotary vane steering gear

摘要：

Aiming at the rapidity control problem of Direct Drive Electro-Hydraulic (DDEH) servo Rotary Vane Steering Gear, a design method of Quantitative Feedback Theory (QFT) controler is proprosed. The QFT controller is introduced to solve the problem of the uncertain parameter and external disturbances of the system. After creating the DDEH servo rotary vane steering gears model, the controller was designed based on QFT, in which the input pre-filter transfer function F(s) and proper controller G(s) are designed. The experimental results show that the proposed method has good control performance to attenuate the parameters perturbation and external disturbance, enhances systemic robust performance and unknown disturbance can also be greatly compensated.
