Consider the furnace shown below, used to heat the supply air to a catalyst regenerator. The following response data were obtained for a step change of 5 % in the output of the controller given at t = 0.5 min.

a) Draw the complete block diagram specifying the units of each signal to/from each block. Identify each block and specify the fail-safe position of the valve and the correct sign of the controller gain. Neglect the measurement and valve dynamics. b) Fit a 1st order + dead time process transfer function to the process. c) Tune PI and PID controllers to the process.
