摘要
步进电动机在起动过程中,需要对其输入的脉冲频率进行控制,使其能准确定位且起动时间尽可能短.在分析步进电动机的矩频特性、系统的运动方程式的基础上,建立脉冲频率优化控制的数学模型、最佳起动频率的数学模型和最高运行频率的数学模型,并计算获得脉冲频率优化控制曲线.
It is necessary to control the pulse frequency inputted to stepper motor in startting process,to enable stepper motor to position accurately and start in the shortest time. Pulse frequency optimal control mathematics model, optimal startting frequency' s mathematics model and maximum operating frequency' s mathematics model are established based on the analysis of stepper motor' s torque-frequency characteristic and systemic motion equation. Pulse frequency optimal control curve is drawn by calculating.
