Abstract
This paper describes the design, simulation and testing of a
piezoelectric spool valve. An actuator has been connected to
the valve and tested under closed loop control. A mathematical
model of the valve was produced and a prototype of the valve
was tested. The mathematical model is validated against the
experimental data. Step and frequency responses for both the
valve and actuator are presented. It was found that
displacement of the hydraulic fluid by the ring bender had an
impact on the valve performance. To reduce the effect of the
piezoelectric hysteresis, closed loop spool position control was
evaluated. A noticeable difference can be observed between
open loop and closed loop performance
