英文摘要：

In order to improve the stability and performance of multi-wing autonomous underwater vehicle′s attitude control,An attitude control system with all parameters was designed for the multiwing autonomous underwater vehicle to research multi-wing control methods.Firstly,through the dynamics and kinematics analysis of multi-wing autonomous underwater vehicle,its motion control model with all parameters was established;Then on this basis,the whole control system model of the underwater vehicle was built and the attitude control system based on linear quadratic regulator was designed;At last,the simulation experiments of attitude control were conducted,and the results showed that multi-wing autonomous underwater vehicle could rapidly follow the target attitude with stability in the case of some external disturbances,the established attitude controller and the control model could meet the autonomous control requirements of the multi-wing underwater vehicle,which was verified to achieve the purpose of controller design.
