Hello all,
I have a simulink model for an autonomous microgrid which has no input and no output and I I would like to get the system poles at a certain operating point using the control system design tool in MATLAB. However when I start this tool with linearization, it demands specifying system inputs and outputs (There are currently no linearization I/Os marked on the model) to get the A B C D matrices which is not applicable in my model... So, how could I employ this tool to get the system modes ?
Use 1st Principles to model the system using KVL/KCL then find state equations for your microgrid. Use the state space to find your eigenvalues/eigenvectors which will give you the poles
If your simulink model is based on differential and algebraic equations, then you can use 'linmod' MATLAB command to linearize it.
