摘要： When a move command (data indicating to move a movable unit from one position to a target position) is issued, a movable unit is displaced in response to the move command. A target trajectory which is an aggregation of target positions varying with time is determined such that a residual vibration of a structure at and after the stop of displacement of the movable unit is minimized. Target positions at various times during the displacement of the movable unit are generated based on the target trajectory. The target positions at various times are supplied to a control unit which feeds back an actual position of the movable unit and produces a drive signal which makes a difference from the target position zero. The drive signal is supplied to an actuator so that a drive force is transmitted from the actuator to the movable unit which follows a change in the target position. As a result, the movable unit is moved to the target position and the vibration at and after the stop of movement is suppressed.

摘要： A method to automatically identify the inertia of an actuator (and the like) and load for tuning an observer-based controller is presented. The tuning is a one-time process that is initiated by a user when the actuator is installed. The control includes a model of the actuator with state feedback to set the desired dynamics.

摘要： A machining-error of a non-circular shape machining apparatus is corrected by controlling a movement of a tool which is synchronous with a rotation of a workpiece. A position of the tool is detected when the tool is according to a command position which is coincident with or close to a target position of the tool. At least an amplitude ratio and a phase difference of an amplitude ratio, a phase difference, and an offset difference between the target position and the detected position; is obtained. At least a process of increases and/or reducing the command position and a process of phase shift of the process for increasing and/or reducing the command position on the basis of the amplitude ratio, a process for shifting a phase on the basis of the phase difference, and a process for changing an offset of the command position on the basis of the offset difference are performed, whereby a first corrected command position is obtained. The detected position of the tool can be made to coincide with the target position quickly since the target position and the detected position are determined as a waveform, which is divided into an amplitude, a phase, an offset and a distorsion.

摘要： According to one embodiment, a robot control device is used for a robot arm including a link and a motor for rotationally driving the link. The robot control device includes a derivation part. The derivation part derives a first estimated value including a variation of a rotation angle of the link and a second estimated value including a variation of a rotation angle of the motor, based on an angular velocity and a current reference value of the motor. Furthermore, the derivation part derives an external force generated to the robot arm, based on a difference between the first estimated value and the second estimated value.
