Comparison of Soft-Landing Position Control and Energy Minimization Performance of Two Fluid-Control Solenoid Valves

摘要

This paper considers low-energy solenoid actuators for application in an automotive fluid-control valve. A permanent magnet-biased (PMB) topology is compared to a classical reluctance actuator (CLA) using magnetostatic simulation data regarding their merits in closed-loop control position tracking, soft-landing, and energy consumption. The PMB topology achieves similar position-tracking as CLA, with the added benefit of reducing the energy demand by at most 63 %.
