查询词典 angle pitch

For controlling the angle of pitch and velocity of rotate shaft of helicopter,the control performance of fuzzy PID,neural network PID and immune PID is compared each other.The simulation results show that neural network PID controller has the highest accuracy.

针对直升机俯仰角度控制和旋转轴速度控制需求，对模糊PID控制、神经网络PID控制和免疫PID控制在不同控制规律下的系统控制效果进行了对比研究。

The paper uses the strategies of pitch angle control and rotational speed control. For the rotational speed controller, vector control method in the dq synchronous rotational frame was employed.

系统采用了桨距角控制和发电机转速控制策略，而发电机转速控制采用了dq同步旋转坐标系下的矢量控制。
