Change the transfer function of the Reference Filter block. Set the Numerator

parameter to 100 and the Denominator parameter to [1 20 100].

set_param('scdspeedctrl/Reference Filter','N',"100");

set_param('scdspeedctrl/Reference Filter','D',"[1 20 100]");

Since the model parameters have changed, trying to find an operating point that meets

the specifications in opspec using the following command generates an error.

op = findop(sys,opspec);

Update the operating point specification object to reflect the changes in the model.

opspec = update(opspec);

Find an operating point that meets the updated specifications.

op = findop(sys,opspec);
