| 摘要 |
A stepper motor controller which can control the motor to stop rapidly and with minimum overshoot and oscillation at a selected position by turning on and off one or several coils in a binary fashion to force the motor to conform to a predetermined position/velocity profile, resulting in the motor velocity and the position deviation from the null point to converge to zero at the selected null point. An encoder continuously generates current position and velocity data, a comparator compares the current velocity and position to a predetermined velocity/position profile to produce a binary output, and one or several motor coils are energized to drive the current motor velocity toward the predetermined value. |
