Draw the output response of the expected closed-loop responses of the system to a unit step input change in setpoint for kc = 0; kc = 1; kc = 10 and kc = 100. for time use: 0  t  5 changing by 0.5. (16) 4.2 use process control software to plot the output response for y(t) for a unit step input change in setpoint. write down the code you have used to determine the output response.
