提出一种基于偏差分离的双线性控制策略,并将其应用到小型无人直升机的航向控制中.双线性控制策略把系统模型分解为两部分:线性模型和不确定项.用偏差分离结构获取不确定项的信息.控制器也由两部分组成,一部分根据线性模型设计常规线性控制器;另一部分则基于不确定项的信息设计线性补偿控制器.仿真结果表明了所提出的双线性控制策略的有效性.
Bilinear control strategy based on model bias separation is proposed,and it is applied to the yaw control of small-scale unmanned helicopters.The system model is divided into two parts:linear model and uncertainty.The information of uncertainty is online obtained by the novel structure of model bias separation.The controller is the integration of a conventional linear controller with a linear compensator.The simulation results verify the effectiveness of the proposed bilinear control strategy.
