How to put this transfer function into simulink
显示 更早的评论
How can I put this transfer function -(1-0.5*e^(-10s)) / (40s+1)(15s+1) into a transfer function block in simulink.
Mainly confused about how to handle the numerator and whether or not I can use just a transfer function block
or if I can use a transport delay block as well.
Thank you!

The transfer function in question
syms s
H(s) = -(1 - 0.5*exp(-10*s))/(40*s + 1)/(15*s + 1)
Starting from a single input signal:
Feed the input signal into a Transport Delay block to implement the 10 second delay. Make sure to set the iniial buffer size large enought relative to the step size of the simulation.
Multiply the output of the time delay by a Gain of 1/2
Feed the input signal into a Gain of -1
Sum togther the outputs of the two Gain blocks
Feed the output of the Sum block into a Transfer Function block. The Numerator is 1. The Denominator is: conv([15 1],[40 1])
