Abstract
A solenoid assembly includes a solenoid actuator having a core. A coil is configured to be wound at least partially around the core such that a magnetic flux (ϕ) is generated when an electric current flows through the coil. An armature is configured to be movable based on the magnetic flux (ϕ). A controller has a processor and tangible, non-transitory memory on which is recorded instructions for controlling the solenoid assembly. The controller is configured to obtain a plurality of model matrices, a coil current (i) and an eddy current (i). The magnetic flux (ϕ) is obtained based at least partially on a third model matrix (C), the coil current (i) and the eddy current (i). Operation of the solenoid actuator is controlled based at least partially on the magnetic flux (ϕ). In one example, the solenoid actuator is an injector.
