摘要： A sheet transport apparatus includes: a first motor and a second motor; a first roller configured to: rotate upon receiving motive power from the first motor; and transport a sheet in a predetermined transport direction; a second roller which is provided on a downstream side of the first roller in the transport direction and which is configured to: rotate upon receiving motive power from the second motor while nipping the sheet transported by the first roller at a nip position; and transport the sheet further downstream in the transport direction; and a controller. The controller includes a motor control unit configured to perform a first process for rotating the first roller and a second process for rotating the second roller; and a first reaction-force estimating observer configured to calculate a first estimated value which is an estimated value of a reaction force acting on the first motor.
摘要翻译： 片材输送装置包括：第一电动机和第二电动机; 第一辊，其构造成：在接收到来自所述第一电动机的动力时旋转; 并在预定的输送方向上输送片材; 第二辊，其沿输送方向设置在第一辊的下游侧，并且构造成：在将由第一辊传送的片材夹在辊隙位置的同时接收来自第二电动机的动力的旋转; 并在输送方向进一步向下游输送片材; 和控制器。 所述控制器包括：马达控制单元，被配置为执行用于旋转所述第一滚子的第一处理和用于旋转所述第二滚筒的第二处理; 以及第一反作用力估计观察器，被配置为计算作为作用在第一电动机上的反作用力的估计值的第一估计值。
