摘　　要：本设计以微控制器AT89C52为核心,用直线差补和圆弧插补法实现电机的控制。在充分考虑非电因素引起运动误差的基础上,根据规定的运动轨迹,建立完善的数学模型。在软件方面,为了有效解决汇编语言除法运算引起的程序的复杂性,巧妙地通过查表方法,把除法运算转化为定点数加法运算,大大简化了编程量。驱动电路均采用光电耦合器隔离以避免干扰,软件部分利用抗干扰技术进行优化,提高系统可靠性。In this study, a microcontroller AT89C52 is taken as a center, the motor control are realized by linear differential compensated and cirsular plugged compensated method. Based on nonelectron factor cause the kinematic error from consideration and prescreption kinematic locus, the mathemation model are established. In software, for solution assembly language division calculation into fixed point which make the program complexity, translation division calculation into fixed point data add calculation by look up table method, the programining are simplified. For avidance interference use of the photoelectrical coupler isolation in drive circuit, optimization software by the anti-interference-techque, the system reliability are raised.
