Return the series connection (sysn * … *) sys2 * sys1
Return type: Raises:
ValueError– if sys2.inputs does not equal sys1.outputs if sys1.dt is not compatible with sys2.dt
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.
>>> sys3 = series(sys1, sys2) # Same as sys3 = sys2 * sys1
>>> sys5 = series(sys1, sys2, sys3, sys4) # More systems
