摘要

给出了利用利萨结评价三维旋转形式的一种方法。确定了SO(3)的最优参数化,使机器人姿态系统更加有效。给定机器人的局部平移速度和局部角速度,利用旋转形式对机器人轨迹进行数值积分。将得到的轨迹与机器人的真实轨迹进行比较,将数值误差、积分时间和步数作为参数化方法的评价标准。

Evaluation of rotation formalisms in three dimensions using a Lissajous knot
An evaluation of three dimensional rotation formalisms using a Lissajous knot is given. The optimal parameterization of SO(3) is determined so that robotics attitude system can become more effective. Given a robot's local translational velocity and local angular velocity, numerical integrations along a robot's trajectory using rotation formalisms are performed. Comparing the resulting trajectory with a robot's true trajectory, this paper considers numerical error, integration time and steps as parameterization methods' evaluation criteria.
