The transient nonlinear fields in the coupled problem are analyzed by finite element method and the magnetic saturation, eddy current and armature movement are taken into consideration. The nonlinear electronic control loop is re-expressed by the equivalent circuit equation coupled with the magnetic subsystem. Iteration method for parallel computing. And the simulation and experimental comparison, the predicted high-speed electromagnetic switching valve performance and experimental results are consistent
