transfer_function¶
Returns an interpolatory state-space model based on the transfer function
method [1]. This method is general and is, effectively, a wrapper of the
sharpy.linear.src.libss.join()
method.
Features:
stability preserved
system size increases with interpolatory order, but can be optimised for fast on-line evaluation
- param SS_list
List of state-space models instances of
sharpy.linear.src.libss.ss
class.- type SS_list
list
- param wv
list of interpolatory weights.
- type wv
list
Notes
For fast online evaluation, this routine can be optimised to return a class that handles each state-space model independently. See ref. [1] for more details.
