【摘要】 针对现有的步进电动机速度控制规律不易实现、灵活性较差等问题，提出了用定时方法实现指数型最佳升降频的控制．试验证实了所提方法的正确性和可行性．更多还原

【Abstract】 Aiming at such limitations as being difficult to implement and poor in flexibility in common speed control methods, the author puts forward the exponential optimal speedup-slowdown rule with the time-lapse method. Experiments have been done to validate the correctness and feasibility of the method.更多还原
