b. Construct the control block diagram of the given process in Figure 1 with clearly labelling all signals and blocks. The detail descriptions of control elements were tabulated in Table 1. Control elements Process Controller Table 1 Details of control elements Design Conditions Second order system with gain 5 kg/hr/c, time constant of 15 sec and damping ratio of 2.5 Temperature controller of proportional-integral (PI) with gain 35 %C0/%TO and integral time is 10 sec Temperature sensor is calibrated from 120 to 200C First order plus dead time system with gain 3 kg/hr/%CO, time constant of 4 sec and time delay of 1.8 sec First order system with 6.2 kg/hr/C and time constant of 5.2 sec Transmitter Control Valve Disturbance (7 marks)
