This programme is to control DC motor in a certain speed using PWM. The target speed is \"r\", it is the speed in 1s. The sample rate is 0.1s, so the actual speed target is \"rc\"=r/10. The \"r\" and \"rc\" are integer, and the range of \"r\" i

利用DSP的PWM1和PWM2,然后经过了两级放大控制直流电机，若要改变电机转速或转向,可在DSP28_EV.c文件里按相应注释修改，即实现PWM波来控制电机。-Using DSP-PWM1 and PWM2, and then amplified through a two DC motor control, to change the motor speed, or steering, can DSP28_EV.c file comments by corresponding changes

在交流电机变频调速中，脉宽调制技术已经得到了广泛的应用。而空间矢量脉宽调制方法与经典的脉宽调制方法相比，具有直流电压利用率高、控制简单、损耗较小、便于数字化方案实现等优点。文中介绍了利用TI 公司的DSP 电机控制芯片TMS320F2812 实现SVPWM 的方法。该控制方法速度快、精度高，在电压型逆变器中能产生更少的谐波并减少开关损耗。-AC motor speed regulation, pulse-width modulation technology has been widely us
