The file is simulink model for speed control of induction motor using Direct torque control method.

Permanent magnet synchronous motors (PMSM) are appropriate for applications with load-independent speeds or synchronous operation with high accuracy under defined speed. In this paper analysis the structure and equations of the PMSM, direct torque

1、本程序用于测试4相步进电机常规驱动 2、需要用跳帽或者杜邦线把信号输出端和对应的步进电机信号输入端连接起来 3、速度不可以调节的过快，不然就没有力矩转动了 可以按照给的原理图接线 接P1.1-P1.4-1, the procedure used to test conventional drive 4-phase stepper motor 2, with a the jump cap or the DuPont line stepper motor signal

单片机步进电机控制程序 通过脉冲数控制电机转速和转矩 -Single-chip stepper motor control program to control motor speed and torque by the number of pulses
