scipy.signal.StateSpace

class scipy.signal.StateSpace(*system)[source]

Linear Time Invariant system class in state-space form.

Represents the system as the first order differential equation \(\dot{x} = A x + B u\).

Parameters:

*system : arguments

The StateSpace class can be instantiated with 1 or 4 arguments. The following gives the number of input arguments and their interpretation:

Notes

Changing the value of properties that are not part of the StateSpace system representation (such as zeros or poles) is very inefficient and may lead to numerical inaccuracies.
