摘要
Methods and systems for performing sheet registration are described. A device having a plurality of drive rolls (325) may receive a sheet. Each drive roll may operate with an associated angular velocity. A state vector, including a plurality of state variables, may be identified. Error-space state feedback values may be determined based on a difference between each state variable and a corresponding reference state variable based on a desired sheet trajectory. Control input variable values may be determined based on the error-space feedback values and one or more gains. A motor control signal for a motor for each drive roll may be determined based on the control input variable values and the state variables. Each motor control signal may impart a desired angular velocity for at least one drive roll. The identifying step and each determining step may be performed repeatedly to register the sheet to the desired trajectory.
