Abstract: A robot motion data processing system has a data extraction module for intermittently extracting restoration motion data from a successive input motion trajectory formed for controlling a motion of a robot, and a data restoration module for restoring an output motion trajectory approximate to the input motion trajectory by using restoration motion data extracted from the data extraction module. The output motion trajectory is restored to satisfy a condition that the robot operating according to the output motion trajectory does not exceed a hardware operation limit of the robot.

Abstract: Provided is a controller of a robot manipulator, a performance analysis method thereof and a parameter determination method thereof. The controller computes an error value of an output value of a control target for a target value through a computational equation and provides a control input value of the control target, and includes an outer loop controller which constitutes closed loop control of the control target, and an inner loop controller which performs feedback linearization to remove nonlinearity of the control target, wherein the computational equation is a linear differential equation designed considering exogenous disturbance acting in the controller and a computational error.
