LOW PRESSURE SIGNAL SENSOR AMPLIFIER AND ANALOG COMPUTER USING THE IMPACT MODULATOR AS THE BASIC ACTIVE PURE FLUID DEVICE. PART I. ANALOG COMPUTER.

Abstract

Fluidic operational amplifiers and integrators have been designed and tested. The amplifier gains and integrator rate gains are shown to depend only upon the passive circuitry. First and second order linear differential equations with constant coefficients have been solved with these computing devices. Deviations between the computed and calculated first order solutions were less than 2%. Second order equations with damping greater than 0.8 also showed errors of 2% or less. Damping less than 0.8 but greater than 0.4 had less than 5% error, and lighter damped systems, including zero damping, showed errors of 8% or less. Suggestions have been made for system accuracy improvement, and also for extensions in the state of the art for fluidic computing systems. (Author)
