WebPython equivalent of MATLAB tfest (but the algorithm is not exactly the same) Only works with SISO systems for now. Installation: pip install tfest. Example: To get a scipy transfer function: import tfest # u: input # y: output te = tfest. tfest (u, y) # n_zeros, n_poles te. estimate (3, 4, time = 1) te. get_transfer_function WebI found the function tfest in the System Identification Toolbox. It allows you to define the number of poles, the number of zeros, and even some delay. However, I am wondering if it is possible to force the transfer function to have a certain structure. For example, H ( s) = H 1 ( s) + α e − τ s H 2 ( s).
