Spring-Mass System: Calibrate Parameters
Understand the dynamics of a spring-mass system. This example uses a cellphone, attached vertically to a spring, to record accelerations. The experimental data is then used to calibrate the model parameters.

Carry out an experiment where you suspend a cellphone vertically connected to a spring.
The phone starts from rest, with its initial position 30 mm below the equilibrium. When the phone is released, it oscillates a few times before coming to a standstill.
Create a Model
Create a model of the spring-mass system.
The model is created using components from the MultiBody library.
Calibrate Parameters
Use the SystemModelCalibrate function to calibrate model parameters.
The measurement data is passed to the SystemModelCalibrate function as a reference.
