The application of a PID parameter tuning method based on model matching on frequency domain for printer ink-head speed control

Nowadays, control technologies are used in many fields, such as industrial plants, industrial robots, home electronics, cars, etc. Many control methods, like the robust control, the optimal control, and the fuzzy control, etc., are proposed. However, a PID controller is used about 90% of the time as the control method. The ink-head of an ink-jet printer which is widely used at home is controlled by the PID controller. However, PID control parameters have to be readjusted when the dynamic characteristics of the printer are changed for each target, because PID controller parameters are adjusted by trial and error technique. Thus the tuning task requires a lot of time and is a tedious job. In this paper, a tuning method based on model matching on frequency domain is applied to determine PID controller parameters for the ink-head speed control of a printer, and experiments with an actual printer are implemented.
