    摘要: A motion control system and method are disclosed which provide improved pulse placement for smoother operation of a motion device such as a stepper motor. A placement of pulses may be determined for each of a plurality of time intervals such that the pulses are placed evenly across the plurality of time intervals, wherein the quantity of pulses in each of the time intervals is variable. The pulses may be generated and sent to the motion device to move the object to the desired position. A delay may be used to place each pulse at an arbitrary location within one of the time intervals. Where the desired step rate is fractional, time may be nullborrowednull for one loop iteration from other loop iterations. In one embodiment, the step rate may be changed from one loop period to the next.

    摘要: A motor control positioning apparatus and method are disclosed wherein variable duration pulses are fed to a DC motor. After the vicinity of the destination has been reached, the final pulsing stage is initiated, in which a short duration pulse is fed to the motor; position is then checked to determine if forward movement of the driven element has occured; and if movement has not occurred, the pulse duration is increased by an increment which is repeated until movement does occur. Thereupon a new series of such pulses is started; and this cycling continues until destination is reached.
