OutputResponse issue

Can anyone help me with the following issue?

Plot[Chop@OutputResponse[TransferFunctionModel[0.53/(0.53+2 s+3 s s+s s s),s],UnitStep[t],t],{t,0,10}]

which returns

OutputResponse::nsymb : "0.0002042857142857143` must be a symbol. \
Appearance->{Automatic, None},

and several other msgs.

I have tried a different approach

restfmf[t_,k_]:=OutputResponse[TransferFunctionModel[(k 1.06)/(k 1.06+2 s+3 s s+s s s),s],UnitStep[t],t];

Plot[Chop@Evaluate@restfmf[t, 0.5], {t, 0, 10}]

but got the same error messages

What am I missing here?

Many thanks
