Abstract

ER clutch is a device using electro-rheological fluid which is one of so called intelligent materials. Power transmission behavior of an ER clutch can be controlled by electrical field applied tb the fluid. In this work, a new type of servomechanism is developed with two ER clutchs, driven by two electrical motors rotating in reverse directions. The concentric cylinder type ER clutch is operated by PID control. The system shows good angular position control characteristics with respect to sinusoidal and square inputs.
