This research investigates the dynamic performance of Electro-Controlled Actuation (ECA)-integrated poppet and spool valve systems, focusing on real-time position control and response behavior under experimental conditions. The study aims to evaluate and compare the transient characteristics, stability, and controllability of both valve types when actuated through ECA mechanisms, specifically incorporating magnetorheological (MR) fluid-based actuators. Two prototype systems were developed—one utilizing a poppet configuration and the other a spool configuration—each equipped with a translational component that extends out of the MR fluid chamber to enable precise position measurement. A position sensor captures the motion of this translational piece and relays data to a digital controller, which in turn modulates the driver circuit to adjust the magnetic flux density within the actuator assembly. Results demonstrate that while both configurations benefit from ECA integration, the poppet valve exhibited faster response times due to its simpler mechanical structure, whereas the spool valve provided more stable flow control under steady-state conditions. The findings contribute valuable insights into the selection and optimization of valve types for high-performance fluid power systems, emphasizing the potential of ECA technologies in enhancing precision and adaptability.
