Total combined I/O delays for LTI model
td = totaldelay(sys)
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.
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
This is equivalent to assigning an I/O delay of 3.5 seconds to the original model sys.
