control.dcgain¶
- control.dcgain(*args)¶
Compute the gain of the system in steady state.
The function takes either 1, 2, 3, or 4 parameters:
Parameters: A, B, C, D: array-like
A linear system in state space form.
Z, P, k: array-like, array-like, number
A linear system in zero, pole, gain form.
num, den: array-like
A linear system in transfer function form.
sys: LTI (StateSpace or TransferFunction)
A linear system object.
Returns: gain: matrix
The gain of each output versus each input:
Notes
This function is only useful for systems with invertible system matrix A.
All systems are first converted to state space form. The function then computes:
