ABSTRACT:
A closed loop feedback control for enhancing the response of electrorheological fluid having a light source and a photodetector measuring the light transmission through the electrorheological fluid. A manually controllable signal generator generates a reference signal indicative of the desired transmission through the electrorheological fluid. A control amplifier responsive to the difference between the measured transmission and the reference signal changes the value of the electric field being applied across the electrorheological. The change in the electric field selected to significantly reduce the time required for the electrorheological fluid to change from its current state to the desired state.
