Investigation of the Active Control of Helicopter Structural Vibration with Online Secondary Path Modeling

提出一种基于误差通道在线辨识的有源控制方法,并把它应用于直升机结构振动的主动控制。针对一直升机模型与前人的方法进行了比较,并进行多输入多输出的主动控制仿真。仿真结果表明,这种控制方法明显优于前人的方法,说明这种基于误差通道在线辨识的多输入多输出的主动控制方法对直升机结构振动有很好的抑制作用。

An active control strategy with online secondary path modeling is proposed and applied in active control of helicopter structural vibration. It is compared with existing method based on a helicopter model, and MIMO active control simulation is conducted. The results show that the proposed method can produce superior performance compared with the existing method and reduces the structural vibration of helicopter effectively.
