| 摘 要： | 采用一种基于输出反馈,部分状态反馈和奇异摄动理论的近似解耦方法设计一个高增益比例积分控制器来实现对多变量系统的解耦控制.所得控制器结构简单,且解耦后的系统能得到良好的动态响应和较强的鲁棒性.文中以经改装后具有直接侧力操纵面的某型飞机为例,对其侧向平移模态进行了解耦控制设计,并将其应用于该飞机的阵风减缓.最后与不具有直接侧力操纵面的原飞机进行仿真对比.仿真结果表明,其产生的均方根阵风加速度比原飞机减少了约55%.

| Abstract: | The approximate decoupling method utilizes output feedback,partial state feedback and singular perturbation theory to design a high gain proportional plus integral controller which has simple structure and provides the decoupled system with desirable dynamic response and good robust stability.The method is used to design a lateral transition mode for a certain aircraft with active-control surfaces.And a gust load alleviation control system is designed based on the lateral transition mode.Simulation result s... |
