control.matlab.lsim
- control.matlab.lsim(sys, U=0.0, T=None, X0=0.0)[source]
Simulate the output of a linear system.
As a convenience for parameters U, X0: Numbers (scalars) are converted to constant arrays with the correct shape. The correct shape is inferred from arguments sys and T.
- Parameters
sys (LTI (StateSpace, or TransferFunction)) – LTI system to simulate
U (array-like or number, optional) –
Input array giving input at each time T (default = 0).
If U is
None
or0
, a special algorithm is used. This special algorithm is faster than the general algorithm, which is used otherwise.T (array-like, optional for discrete LTI sys) – Time steps at which the input is defined; values must be evenly spaced.
X0 (array-like or number, optional) – Initial condition (default = 0).
- Returns
yout (array) – Response of the system.
T (array) – Time values of the output.
xout (array) – Time evolution of the state vector.
Examples
>>> from control.matlab import rss, lsim
>>> G = rss(4) >>> T = np.linspace(0,10) >>> yout, T, xout = lsim(G, T=T)
