摘要

Aiming at the rapidity control problem of Direct Drive Electro-Hydraulic (DDEH) servo rocket rudder, a design method of Quantitative Feedback Theory (QFT) controller with friction torque dynamic compensation is proposed. The QFT controller is introduced to solve the problem of the uncertain parameter and external disturbances of the system. After creating the DDEH servo rocket rudder's 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 simulation 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.
