Abstract
There is provided a transport system including: a transport mechanism including first and second rollers; first and second driving devices; first and second measuring devices configured to measure a state quantities Z1 and Z2; and a controller configured to control the first and second driving devices. The controller is configured to perform: estimating reaction forces R1 and R2; calculating control inputs U1 and U2; inputting, to the first driving device, a control signal in accordance with a sum of the control input U1 and the control input U2; inputting, to the second driving device, a control signal in accordance with a difference between the control input U1 and the control input U2; estimating non-tensional components RE1 or RE2; and correcting the control input U2 to prevent a control error caused by the non-tensional components RE1 and RE2 included in an estimated tension of the sheet (R1−R2)/2.
