摘　　要：采用专用芯片和单片机设计了一种全数字化的无刷直流电机伺服系统。利用无刷直流电机的位置传感器信号倍频后,用于伺服系统的转速反馈,大大简化了系统结构。本文还介绍了利用遗传算法搜索PID转速控制器最优参数的方法,并给出了实验结果。This paper proposed a fully digitalized Servo-System using intensive controller arid a 8-bit MCU with a BLDC as its motivity. By using the signals from the build-in position sensors of BLDC after Frequency-Multiplied as its speed feedback signal, the complexity of system is significantly decreased. The genetic arithmetic was used to optimize the parameters of the speed PID controller. At last the experimental result was given.
