ABSTRACT:
An actuating control device for use between a printer head and an actuating and transmitting device includes a path planning unit, a feedback unit, a proportional-integral controller and a feed forward controller. The path planning unit issues a position command value and a speed command value. The feedback unit generates a position feedback signal and a speed feedback signal according to the position and the speed of the printer head. The proportional-integral controller generates a first control signal according to the difference between the position command value and the position feedback signal and the difference between the speed command value and the speed feedback signal. The feed forward controller generates a second control signal according to a computation on the speed command value. The printer head is driven to move by the actuating and transmitting device in response to the first control signal and the second control signal.
