摘要

分析了现有的飞行器偏航动力学建模方法，提出了一种新的面向控制的模型。这些车辆偏航动力学模型都是通过简化车辆原始物理动力学得到的，它们各有优缺点。针对飞行器偏航稳定性控制问题，提出了一种基于观测器的非线性严格反馈飞行器偏航动力学建模方法。并在非线性仿真软件中对模型进行了进一步的验证，验证了所提模型适用于横摆稳定控制器的设计。

Vehicle yaw dynamics modelling and analyzing for yaw stability control

Some vehicle yaw dynamics modelling methods are analyzed and a new control-oriented model is proposed in the paper. These vehicle yaw dynamics models are all obtained through simplifying vehicle original physical dynamics, and they all have strong and weak points. Considering vehicle yaw stability control problem, a new observer-based vehicle yaw dynamics modelling approach for controller design is proposed, which is nonlinear and strict-feedback. And these models are further evaluated in a nonlinear vehicle simulation software, and it is testified that the proposed model is proper for yaw stability controller design.
