base coordinate system

基本解释

According to feather element tree, the base level and base coordinate system are created, then we can choose them when we need them at any time.
根据特征元素树创建了基准面和基准坐标系，使我们很方便的在需要参照基准的时候来选取它。
The paper design the control system of the DPC model base on MIMO feedback linearization theorem under the static DQ Coordinate and the rotating dq Coordinate.
为便于控制系统设计中消除非独立的状态变量，本文对得到的模型进行了相应的旋转dq变换和静止DQ变换；
The merit of this method is to place the base coordinate system in the middle joint to acquire relative Jacobian matrix and make expression of Jacobian matrix simplified.
该方法是将基坐标系建立在中间关节上，从而得到机器人的相对雅可比矩阵，使得雅可比矩阵表达简单。
