Abstract
There is provided a transporting system including two rollers to transport a sheet, two driving devices to drive the rollers, two measuring devices to measure state quantities Z1 and Z2 concerning the rollers, and a controller to control the transport. The controller includes first and second estimating units to estimate values R1 and R2 related to reaction forces act on the rollers, a first calculating unit to calculate control input U1 in accordance with a deviation between a target state quantity and (Z1+Z2)/2, a second calculating unit to calculate control input U2 in accordance with a deviation between a target value and (R1−R2)/2, a first drive controller to input a control signal in accordance with (U1+U2) to the first driving device, and a second drive controller to input a control signal in accordance with (U1−U2) to the second driving device.
