Patent ID: 7131779

Claim:
An actuating control device for use between a printer head and an actuating and transmitting device of a printing apparatus, said actuating control device comprising: a path planning unit issuing a position command value and a speed command value; a feedback unit communicated with said printer head and generating a position feedback signal and a speed feedback signal according to the position and the speed of said printer head; a proportional-integral controller communicated with said path planning unit, said feedback unit and said actuating and transmitting device, and generating a first control signal to be transmitted to said actuating and transmitting device according to the difference between said position command value and said position feedback signal and the difference between said speed command value and said speed feedback signal; and a feed forward controller communicated with said path planning unit and said actuating and transmitting device, and generating a second control signal to be transmitted to said actuating and transmitting device according to a computation on said speed command value, wherein said printer head is driven to move by said actuating and transmitting device in response to said first control signal and said second control signal.
