Abstract
A method for controlling a brushed DC motor includes: determining a speed difference signal based on a difference between a speed command signal and a motor speed; determining an initial voltage command based on the speed difference signal; determining a final voltage command based on the initial voltage command; applying a DC voltage based on the final voltage command to cause the brushed DC motor to turn a lead screw and to move a load along a path; determining a disturbance torque; and offsetting the disturbance torque by at least one of: determining a feedforward voltage command based on a position of the load along the path and determining the final voltage command as a sum of the initial voltage command and the feedforward voltage command; or determining a speed compensation signal based on the disturbance torque and determining the speed difference signal further based on the speed compensation signal.
