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:

1: lti system: (StateSpace, TransferFunction or ZerosPolesGain)

4: array_like: (A, B, C, D)

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.
