Comparison of simulated and measured signals of the electromagnetic coil launcher for micro aerial vehicles

In this paper we describe numerical model and designed construction of the EML consisting of 10 coils with a moving ferromagnetic core inside. Friction coefficients were introduced into the system equations and next we proposed an algorithm which enabled us to fit the numerical model to the constructed device. In the paper we present comparison of the signals from computer simulations and measurements which were taken during laboratory and field trials.
