Lumped parameter modeling of hybrid magnetomotive force electromechanical valve actuator

Article scientifique 2020 Anglais

Résumé

Abstract In this study, an innovative hybrid permanent magnet (PM)/electromagnet (EM) magneto-motive force (MMF) actuator is proposed for variable valve timing camless engines. The proposed design provides a large magnetic force with low energy consumption (startup and valve holding), PM demagnetization isolation, and improved transient response. The modified hybrid valve actuator (MHVA) was designed in ANSYS Maxwell software and validated empirically by prototype. A lumped parameter model (LPM) based on mathematical equations is developed to approximate Finite Element Method (FEM) and experimental results. The LPM is divided into electrical, magnetic and mechanical subsystems that are developed and integrated in MATLAB software. The comparative analysis of LPM, FEM and empirical results confirmed improved dynamic performance and energy consumption.
