摘　　要：为了提高水翼艇纵向运动控制的鲁棒性,采用MIMO闭环增益成形算法设计了鲁棒控制器。给出了水翼艇纵向运动传递函数形式的数学模型,通过镜像映射方法将不稳定模型转换成稳定的数学模型。仿真结果表明,所设计的鲁棒控制器将纵摇角降至了原来的25%并对模型摄动具有鲁棒性。In order to improve the robustness of the longitudinal motion control of hydrofoil, a robust controller is designed using MIMO closed-loop gain shaping algorithm. The transfer function mathematical model for the longitudinal motion of hydrofoil is given and the unstable model is converted into its stable model through mirror-injection method. Simulation results show that the pitching angle is decreased to the 25% of the original value and the designed robust controller has the robustness to the perturbed model.
