    摘要： An image forming apparatus and method are provided for measuring a moment of inertia and friction coefficient in the image forming apparatus. The image forming apparatus includes a printing unit for printing an image on a medium, and a parameter calculating unit for measuring at least one of a current and velocity of a driving motor and calculating at least one of a moment of inertia and friction coefficient of the image forming apparatus. Accordingly, the image forming apparatus can measure the moment of inertia and friction coefficient of the image forming apparatus without a separate measuring apparatus, and it is possible to inspect an assembled image forming apparatus and parts therein to maintain the image forming apparatus in an optimal printing state.

    摘要： A method and apparatus to automatically tune a paper-feeding controller included in a paper-feeding system of a printer by eliminating effects of disturbance and thus accurately and automatically calculating gain of the paper-feeding controller. The method of automatically tuning a controller in a paper-feeding system of a printer using a DC motor includes acquiring input and output data of the paper-feeding system by conducting an open loop test, pre-filtering the input and output data to eliminate a drift offset from the acquired input and output data, identifying a system using the pre-filtered input and output data and inducing a system model and calculating a gain of the controller using the induced system model and controlling a velocity of the paper-feeding system according to the calculated gain. Accordingly, the method can minimize effects of disturbances present in the paper-feeding system of the printer, acquire a more accurate system model, and ultimately, obtain improved control performance.
