1 - How do I analyze the stability of the last case? AFAIK, I cannot use the margin and allmargin Matlab functions as the delay is not in the open loop transfer function ($G_{comp}G_{process}$). In both cases the open-loop transfer function is $1+G_{comp}G_{process}e^{-Ts}$ The open-loop transfer function is the transfer function from the output of the ...
