- A liquid will be heated in a perfectly mixed tank that includes a heating coil using a saturated steam at 120C. Temperature of the mixture is controlled using suitable controller. Temperature of feed stream and flow rate of steam act as disturbance and manipulated variable, respectively and corresponding transfer functions are Gd=s+0.250.05 and Gp=s+0.250.2, respectively. - Draw the block diagram of closed loop (Gm=1;Gf=s+20.1) - Write the expression for closed loop response as a function of Gc. - Fill the following table for the unit step change in set point
