| 摘 要： | 通过月面巡视探测器爬坡轮与地面的相互作用分析,建立月面巡视探测器坡度行驶地面力学模型。根据双闭环直流调速系统工作原理,采用位置式PID控制算法编写了电机驱动仿真模块,并将电机驱动仿真模块融合到月面巡视探测器多体动力学仿真体系中,构建了完整的月面巡视探测器动力学仿真系统。对月面巡视探测器坡度行驶工况进行仿真分析,初步实现了对月面巡视探测器动力学模型的验证,为月面巡视探测器驱动控制算法、运动规划和路径规划仿真提供技术支持。

| Abstract: | Lunar rover driving terra-mechanic model was established based on the analysis of interaction be- tween the lunar rover climbing wheel and the ground. Amotor-driven simulation module was then programmed using the positional PID control algorithm according to the working principle of the double loop DC speed control system. Moreover, it is integrated into the multi-body dynamic simulation system, and constructs a complete lunar rover dy- namics simulation system. Finally, the lunar rover driving dynamics model is verified preliminarily by the analysis of the lunar rover slope driving simulation for providing technical support for the driving control algorithm, motion plan- ning and path planning simulation of the lunar rover. |
