You may try the following

1. Let the required transfer function be (1+s)/(1+2s^2). You may define this as

set_param('testmodel/Transfer Fcn','Numerator','[1 1]','Denominator','[2 0 1]')

2. Adding negative feedback

add_line('testmodel','Transfer Fcn/1','Sum/2','autorouting','smart')

3. Increase ports of scope

set_param('testmodel/Scope','NumInputPorts','2')

4. To tune PID contoller, you may use pidtune function
