Abstract
This disclosure describes determination of a fundamental cutoff frequency of a fluidic valve that is independent of the fluidic cutoff frequency. A fluidic test apparatus is set up connecting a fluidic reservoir to one or more fluidic valve(s) and an adjustable load. The valve(s) are switched on and off at a specified actuation frequency. The actuation frequency is adjusted, and measurements are made over a range of different frequencies, e.g., about 0.1 Hz to about 500 Hz. Pressure gain as a function of frequency is determined over different fluidic loads and input pressures and is then utilized in conjunction with fluidic RC models described herein to determine an effective valve cutoff frequency that is independent of the different loads applied on the fluidic valve.
