control.pzmap

control.pzmap(sys, plot=None, grid=None, title='Pole Zero Map', **kwargs)

Plot a pole/zero map for a linear system.

Parameters

  • sys (LTI (StateSpace or TransferFunction)) – Linear system for which poles and zeros are computed.

  • plot (bool, optional) – If True a graph is generated with Matplotlib, otherwise the poles and zeros are only computed and returned.

  • grid (boolean (default = False)) – If True plot omega-damping grid.

Returns

  • pole (array) – The systems poles

  • zeros (array) – The system’s zeros.
