1. A method for constructing a circuit for controlling an electromagnetic actuator, which electromagnetic actuator includes a coil having associated therewith a resistance R1 and an inductance L1, comprising:
- modeling the electromagnetic actuator with an equation;
calculating at least one resistance R2j and at least one inductance L2j, each of which is associated with at least one theoretical coil electrically connected to and physically remote from the electromagnetic actuator, wherein the resistance R2j and the inductance L2j are calculated by satisfying the equation using at least the function;
where ω
21 equals 2π
R1/L1, ω
22j equals 2π
R2j/L2j;
φ
jopen is a switching on phase, φ
jclose is a switching off phase, and j identifies a particular theoretical coil; and
electrically connecting current supply means to the coil of the electromagnetic actuator, which current supply means are configured to substantially simulate the electrical effect of each theoretical coil having the calculated resistance R2j and the calculated inductance L2j.
