| 摘 要： | 对某小型无人直升机的增稳动力学进行了精确的建模,鉴于稳定杆对飞行动力学有很重要的影响,本文对旋翼和稳定杆系统分别进行建模.通过仿真的比较和分析表明,稳定杆引起了姿态系统的小阻尼和峰值,采取加入陷波器的方法进行补偿,使姿态系统的性能得到了明显的优化.

| Abstract: | The paper presents results of dynamics modeling and the attitude control optimization for a small size unmanned helicopter. Especially the rotor and the stabilizer bar are modeled individually. The stabilizer bar improves the stability of the model, and also limit the performance of system. The second order notch filters are used to compensate the light damping and the resonance peak brought by the stabilizer bar, the performance of attitude control system is enhanced consequently. |

| Keywords: | small scale helicopter attitude control optimization stabilizer bar modeling augmentation dynamics |
