Return the total combined I/O delays for an LTI model
Syntax
td = totaldelay(sys)
Description
td = totaldelay(sys)
returns the total combined I/O delays for an LTI model sys. The matrix td combines contributions from the InputDelay, OutputDelay, and ioDelayMatrix properties, (see set or type ltiprops for details on these properties).
Delays are expressed in seconds for continuous-time models, and as integer multiples of the sample period for discrete-time models. To obtain the delay times in seconds, multiply td by the sample time sys.Ts.
Example
sys = tf(1,[1 0]); % TF of 1/s
sys.inputd = 2; % 2 sec input delay
sys.outputd = 1.5; % 1.5 sec output delay
td = totaldelay(sys)
td =
3.5000
The resulting I/O map is
sys.
