control.series¶
- control.series(sys1, sys2)¶
Return the series connection sys2 * sys1 for –> sys1 –> sys2 –>.
Parameters: sys1: scalar, StateSpace, TransferFunction, or FRD
sys2: scalar, StateSpace, TransferFunction, or FRD
Returns: out: scalar, StateSpace, or TransferFunction
Raises: ValueError
if sys2.inputs does not equal sys1.outputs if sys1.dt is not compatible with sys2.dt
Notes
This function is a wrapper for the __mul__ function in the StateSpace and TransferFunction classes. The output type is usually the type of sys2. If sys2 is a scalar, then the output type is the type of sys1.
If both systems have a defined timebase (dt = 0 for continuous time, dt > 0 for discrete time), then the timebase for both systems must match. If only one of the system has a timebase, the return timebase will be set to match it.
Examples
>>> sys3 = series(sys1, sys2) # Same as sys3 = sys2 * sys1.
