Pulsewidth modulation (PWM) control of brushless dc motors is implemented with digital servo mechanisms for robotic applications. Under the assumption that the pulse period is much smaller than the motor time-constants, the motor is modeled by a discrete-time transfer function with the pulsewidth ...
摘要: We present experimental results of a scheme based on the concepts of weak measurements and weak value amplification to measure temporal delays, much smaller than the pulse width, by means of spectral interference.关键词: delays light interference optical variables measurement Iulse width ...
A finite gradient-pulse width delta effectively changes the pore shape, making isolated pores appear smaller than their actual size. The diffraction analogy still holds for long diffusion times, with the fluid density rho(r) being replaced by rho cm(r, delta). This quantity, the ldquocenter-...
If the Bridge Drive changes to a Mark : Space ratio of less than 1, the current takes up a negative average value. With a Mark : Space ratio of greater than 1 it takes up a positive average value. This is also seen in Figure 9.13(b). By varying the PWM pulse width across ...
PURPOSE:To prevent possible measuring error of a measuring apparatus by comparing the first pulse signal with the second pulse signal smaller in the pulse width than the former. CONSTITUTION:An electronic type tape measure 1 is equipped with a keyboard 4, digital display 5 and a buzzer 6 on ...
pulse width, the skin depthδin our sample is calculated to be ~ 1.6 × 10−5 m (see details in Supplementary Discussion5), which is about three orders larger than the diameters of our specimens (typically less than 20 nm, on the order of 10−8 m). Therefore, the current ...
Inshort pulse lasers, the pulsewidth is of the order ofnanosecond. The pulse energy within the pulsewidth or pulse-ON time varies with time. Peak power in short pulse lasers may increase many thousand times than average power. Short pulse lasers generally include Q-switched Nd:YAG lasers,fibe...
divided 407 sets of pulse data into five pulse patterns by using a Bayesian network based on six pulse parameters: depth, width, length, frequency, rhythm and strength (84% successful classification rate)7. Moreover, Xu et al. divided 320 sets of pulse data into 16 pulse patterns by using...
