Publication number: 20030225465Abstract: A system and method 100 of using residual feedback in a control loop in a manner that substantially eliminates the steady state error in the predicted states that results from the mismatch in gain between the plant and the model. The control effort used by the estimator to predict the next position is modified to compensate for this difference in gain. By integrating the residual, and modifying the apparent control effort accordingly, the residual is driven to have a mean value of zero. When the residual goes to zero, by definition, the steady state error in the position state goes to zero; and to the extent that the model matches the plant, the velocity state also approaches zero such that the steady state error in the predicted states are substantially eliminated, allowing for improved control.Type: ApplicationFiled: May 31, 2002Publication date: December 4, 2003Inventor: Eric G.

Patent number: 6564110Abstract: A discrete Kalman filter 12 and a disturbance estimating unit 13 are added to a feedback loop for feeding back a detected value of position from a position detector 6. The Kalman filter estimates position and velocity of an object to be controlled, thereafter outputting an estimated value of position and an estimated value of velocity. The disturbance estimating unit estimates from a command value of current and the estimated value of velocity the disturbance that is added to a load 5. The estimated value of position is fed back to a position controller 1, and the estimated value of velocity is fed back to a velocity controller 2. Further, a difference between a target value of current outputted from the velocity controller and the estimated value of disturbance is output as the command value of current.Type: GrantFiled: June 7, 2000Date of Patent: May 13, 2003Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Kenichi Makino, Yoshiyuki Tomita, Hidehiko Mori

Patent number: 6516247Abstract: A robot is provided, wherein it is possible to reduce incorrect identification in the case of executing face identification in a place where lighting variations are large such as in a house and in a place where there exists a lighting environment that is bad for identification. A face area of a person is detected from an image picked up at an imaging device and stored, and a face detecting and identifying device identifies a person using face image information stored before then. An identification result reliability calculating device calculates, using information from the imaging device, whether or not a present lighting state is suitable for face identification. When the result of calculation indicates that the lighting state is not suitable for face identification, the robot is moved by a moving means. Thereby, incorrect identification can be reduced.Type: GrantFiled: January 29, 2002Date of Patent: February 4, 2003Assignee: NEC CorporationInventor: Junichi Funada
