Testing for frequency response and damping. For arterial line pressure transducers, the "fast flush test" is the clinical bedside test which is used to assess the natural frequency of the system. To return to the model of the transducer system as a simple harmonic oscillator, this "fast flush" is dropping the ball from a height, or giving …

The grid-connected inverter may get unstable due to variation of grid impedance. To improve the system stability, an adaptive active damper, which emulates an adaptive tuning virtual resistor, can be introduced at the point of common coupling. However, subject to the control bandwidth, the virtual resistor is actually a frequency- …
