选定脉冲
The pulse width circuit, which is consisted of the linear heat sensitive resistance, are selected with the pulse width as the time controlling the counting number.
选择线性热敏电阻组成的脉宽电路,将脉宽作为控制计数的时间,由晶振产生某一标准频率的脉冲信号,通过分频以及计算译码驱动送显示。
According to mathematical models of generator and PWM ( Pulse Width Modulation)-control-led wave chopper, the PID ( Proportional-Integral-Derivative) control algorithm is selected by the engineering design method for its regulator.
根据同步机的数学模型、脉宽调制控制的斩波器的数学模型,应用工程设计法确定其调节器的控制算法为比例积分微分(PID)调节。
