| 英文摘要 |
| When the current desired trajectory is similar to a trajectory formed by matching and combining former trajectory
primitives, we put forward a method for determining the initial control signal in the iterative learning control. Firstly,
we subsequently extract from the data base the control signals of corresponding trajectory primitives, and then transform
each control signal by rotation and translation. The linear interpolation method is applied to join the corresponding control
signals of neighboring trajectory primitives to produce the joined trajectory smooth and without interruption in the transition
zone. Thus, the initial control signal in the iterative learning control for the current desired trajectory is determined.
The proposed method is validated by a simulation example based on the XY motion platform. |
