This paper presents a novel deadbeat feedforward compensation technique for fast and precise positioning control in mechatronic systems. The proposed compensation provides the desired frequency shaping in control input to suppress the residual vibration, under the constraint of a specified step number in position reference. A 2-DOF positioning controller with the deadbeat feedforward compensation...
This paper presents a novel deadbeat feedforward compensation in the fast and precise positioning control for mechatronic systems. The proposed compensator is designed considering the frequency shaping in control input to suppress the residual vibration, under the constraint of specified step number in position reference. A 2-degree-of-freedom positioning controller with the deadbeat feedforward compensation...
This paper presents a modeling methodology for unknown disturbances based on a disturbance estimation using a iterative learning process in mechatronic systems. In this research, the nonlinear friction and the modeling errors between mathematical model and actual plant system should be handled as the disturbances in mechanism because these phenomena mainly deteriorate the trajectory control performances...
This paper presents a novel residual vibration suppression methodology for the repetitive fast-response and high-precision positioning in machine tool drives. In sequential positioning motions, as the interval period of position references becomes shorter, the residual vibration in response due to undesired initial values deteriorates the positioning accuracy, since the positioning controller is generally...
