Abstract

Eigensystem Realization Algorithm has been successfully applied to a two-link flexible manipulator for system identification. As has been expected, the time responses of the identified models match perfectly with those of the original one when no noise was added to the measurement data, but the responses of the identified model deviate more significantly from those of the original model as the measurement noise intensity increases.

双连杆柔性机械臂的ERA辨识
将特征系统实现算法成功地应用于两连杆柔性机械臂的系统辨识。正如预期的那样,当测量数据中不加入噪声时,识别模型的时间响应与原始模型的时间响应匹配良好,但随着测量噪声强度的增加,识别模型的响应与原始模型的时间响应偏差更明显。
