三相无刷电机的PWM控制，通过改变下桥臂的占空比来改变电机的转速。-PWM three-phase brushless motor control, by changing the duty cycle under the bridge arm to change the motor speed.

As you have learnt that sleep( )/usleep()/nanosleep() are not good to delay a process. Timers can provide more accurate time control in applications. In this lab, you will explore POSIX timers and signal programming, experience the timer drift. The primary focus of this lab will be "time". The experiment will show you several methods to measure time in your applications.
