Excitation Input

System Response

To excite the system, we apply a discrete chirp signal that sweeps the frequency spectrum from 0.01 Hz to 1 Hz over 50 seconds.

noise is added to reflect a realistic application.

The system response to  can be obtained using the DynamicSystems[Simulate] command. The response can be seen in the following plot.

The Maple commands used to obtain the model-based parameter values are found in the following code edit region.

Using Maple's optimization routines, the parameter values that best describe the physical model were found to be:

The difference in parameter values between those measured and those obtained through the estimation process are shown below.

The plot below shows the frequency response of the measured and the estimated model.
