tf2ss: Transfer function model conversion to State-space model.

In control: A Control Systems Toolbox

Description

tf2ss converts the model for a transfer function to state-space representation

Usage

tf2ss(num, den)

Arguments

num	A numeric vector containing the coefficients of the
den	A numeric vector containing the coefficients of the

Details

tf2ss converts a model object for a transfer function to a state-space model, Where num is the numerator and den is the denominator of the transfer function and sys is a transfer function object

Another possible call is tf2ss(sys) where sys is object of transfer-function model.

Value

Returns an object of 'ss' class.
