直流电机的调速过程如下：本文研究的调速系统选择为经典的晶闸管——电动机转速闭环直流调速系统。由直流电机的实际转速与给定转速进行比较得到的偏差及偏差率送给模糊控制器，由模糊控制器计算出电机控制量，通过调节触发装置的控制电压u来移动触发脉冲的相位，即可改变电压。送给电机，实现电机的转速控制。

-DC motor speed control process is as follows: In this paper, the speed control system of choice for the classic thyristor- closed loop DC motor speed system. The actual speed of the DC motor speed is compared with the given deviation obtained and deviation rate to the fuzzy controller, fuzzy controller calculates the amount of motor control, by adjusting the control voltage u trigger means to move the trigger pulse phase, namely You can change the voltage. To the motor to achieve speed control of the motor.
