Hi Yamelt,

It is my understanding that you are looking for guidance on modeling a parallel RLC circuit driven by a DC current source in Simscape Electrical, and you would like to perform transfer function analysis, stability analysis, and visualize pole-zero plots in Simulink.

If you want to build a parallel RLC circuit with a DC current source in Simscape Electrical, you can use the Electrical Sources library for the current source and the Electrical Elements library for the resistor, inductor, and capacitor components. Connect them in parallel between two electrical nodes. To perform transfer function or frequency-domain analysis, you can linearize your Simscape model using the Linear Analysis Tool in Simulink, which allows you to extract state-space or transfer function representations and analyze poles, zeros, and stability margins.

For plotting poles and zeros, you can use Control System Toolbox functions such as 'pzmap', 'bode', or 'rlocus' on the linearized model. If you are instead looking for time-domain simulation results, you can use Scope blocks or the Simscape Results Explorer to visualize voltages and currents.

You can refer to the following documentations for more information:
