摘要

为了在高速行驶中达到理想的性能,我们不能忽视打滑。系统的运动学和动力学都要考虑。路径跟踪是轮式车辆中最重要的问题之一。在本研究中,我们将讨论阿克曼转向车辆的动力学模型。考虑车辆在平面上运动,根据牛顿定律得到模型。针对非线性系统设计了模糊控制律。最后,在Ackerman转向车辆上进行了模糊控制器测试,结果表明模糊控制器能较好地实现所需的转弯角度,自动驾驶车辆能很好地跟踪轨迹。

Tracking control of autonomous vehicles with slippage
To achieve desired performance during high speed driving, we cannot neglect slippage. The kinematics and the dynamics of a system should all be considered. Path tracking is one of the most important issues in wheel based vehicles. In this study, we will discuss the dynamic model of an Ackerman steered vehicle. The model is obtained according to Newton's laws, considering that the vehicle is moving on a plane surface. Fuzzy control laws are designed for the nonlinear system. Finally, the proposed fuzzy controller is tested on the Ackerman steered vehicle and the results show that the proposed fuzzy controller can achieve the desired turning angle and the autonomous vehicle tracks the trajectory satisfactorily.
