You can use
evalfr(minreal(sys),f)
f is the complex frequency to which you want to take the limit. The minreal is to make sure you cancel common poles and zeros before taking the limit. Be careful if you have poles and zeros that should cancel but don’t because they aren’t quite numerically the same.
