PWM-control-2
- 总之，PWM既经济、节约空间、抗噪性能强，是一种值得广大工程师在许多设计应用中使用的有效技术。-In short, PWM already economy, save space, robust performance is strong, is a kind of worth the engineer in many design application of technology used in effective.
pwm-speed-1
- PWM控制技术以其控制简单,灵活和动态响应好的优点而成为电力电子技术最广泛应用的控制方式,也是人们研究的热点。由于当今科学技术的发展已经没有了学科之间的界限,结合现代控制理论思想或实现无谐振软开关技术将会成为PWM控制技术发展的主要方向之一。-PWM control technology with its simple control, flexible and dynamic response good advantage and makes power electronic technol
pwm-speed-2
- PWM的一个优点是从处理器到被控系统信号都是数字形式的，无需进行数模转换。让信号保持为数字形式可将噪声影响降到最小。噪声只有在强到足以将逻辑1改变为逻辑0或将逻辑0改变为逻辑1时，也才能对数字信号产生影响。 -One advantage of PWM from processor to be control system signal is digital form, there is no need for analog-to-digital conversion. For the signa

- 对噪声抵抗能力的增强是PWM相对于模拟控制的另外一个优点，而且这也是在某些时候将PWM用于通信的主要原因。从模拟信号转向PWM可以极大地延长通信距离。在接收端，通过适当的RC或LC网络可以滤除调制高频方波并将信号还原为模拟形式。 -Noise resistance to increasing ability of the PWM is relative to the simulation control another advantage of, and this also is in some
