**3. Mixed Electrical and Mechanical Model of the Reluctance Coil Gun**

Implementation has been done using Matlab Simulink for this mechatronic model. Simulated inductance and magnetic force values using *FEMM 4.2* are implemented in look-up tables interpolating data in order to have a force and inductance value for any position of the plunger and any coil current. Figure 17 shows the model of a single coil electromagnetic launcher used for simulations. Figure 18 shows the model of a four-coil electromagnetic launcher used for simulations. The mechanical simulation part is unique in both models, whereas the electrical part is replicated by the number of coils present in the electromagnetic launcher.
