The team explored system identification of the fader motor used in previous labs. Rather than measuring a position response to a motor voltage, we decided to explore acceleration response by attaching an accelerometer to the slider. We also added mass to the slider to overcome the effects of friction on the slider. We chose exploring the acceleration response of the system as we thought an accelerometer may be useful for the final project, if accelerometers were used on a drumstick.
The system is represented by a constant K, which is comprised the of motor constant, radius of the gear, and motor resistance, mass of the bolt/accelerometer, damping of the motor and system, and resistance of the motor.
This system is represented by the Bode plot shown below. It should be noted that this system is only a parametrized model and does not incorporate real numbers. It was created to see the shape, not values, of the plot.
