摘 要:研究了一種多螺旋桨推力飞艇的控制问题,首先对螺旋桨和舵偏进行了控制分配,设计了线性自抗扰控制器,并在风干扰下验证了控制效果。介绍了灰狼优化算法的模型和概念,设计了灰狼优化在控制器参数中的优化步骤,对线性自抗扰俯仰角和偏航角控制器进行优化,经过对比分析,灰狼优化在很小的迭代次数下即可得到控制品质较好的控制器参数。

Abstract:The control problem of a multi-propeller thrust airship is studied. Firstly,the control efforts of the propellers and rudders are allocated. A linear active disturbance rejection controller(LADRC) is designed and its control effect is illustrated under the wind disturbance. Then,the model and concept of wolf optimization algorithm is introduced. And the control parameters optimization algorithm is designed based on the wolf algorithm,which is implemented to optimize the LADRC. From the comparation,the wolf optimization can obtain the controller parameters with good control quality in a small number of iterations.
