Double-click on the Sum block. The damping ratio is specified in the denominator of the transfer function, it's not a gain factor. To outline for anyone else with the same issue: 1)Convert tf to state-space model sys_ss=ss (sys) 2)Covert ss model into idss format sys_idss=idss (sys_ss) 3)compare model with data to find initial state state=findstates (sys_idss,data) 4)Use LTI block in Simulink with sys_ss and states gathered. vector P = [-1-1i -1+1i -2] specifies these pole (b) For K =1 and a ramp change in input, u(t)= at, by what time period does y(t . The order of numerator can not be greater than denominator, . (2) . To compensate for disturbance (as per theory), the compensator transfer function should be inverse of the closed-loop controller and plant: This is a second-order transfer function. If the numerator of the block's transfer function is a vector, the block's output is also scalar.
