- The temperature of a catalysed exothermic reaction is being maintained at T1°C as it promotes generation of a particular product. It is proposed to control the temperature with a proportional only controller of gain Kc. The temperature dynamics of the reactor can be modelled as a mixture of a CSTR (1* order) and PFR (dead time) to changes either in inlet temperature, or in the heating/cooling jacket flowrate via Ke-'a® Ts+1 i) Considering a change in inlet temperature show why a 1st order model for a CSTR and a dead time model for a PFR are appropriate. CSTR - continuous stirred tank reactor PFR - plug flow reactorWhich claim is correct? A transfer function model for a stable process always has no time-delay. Feedforward control can be solely used for the setpoint tracking If a process has 3 inputs and 3 outputs, then we need to build 6 transfer function models for it. The inner loop of cascade control has to be slower than the outer loop No correct answerExample 1.1 Figure 1.5 shows the block diagram of a closed-loop flow control system. Identify the following elements: (a) the sensor, (b) the transducer, (c) the actuator, (d) the transmitter, (e) the controller, (f) the manipulated variable, and (g) the measured variable. In the figure above, the (a) sensor is labeled as the pressure cell. The (b) transducer is labeled as the converter. However, there are two converters: one for converting pressure to current, and another converting current to pressure for operating the actuator. The (c) actuator is labeled as the pneumatic valve. The (d) transmitter is labeled as the line driver. The (e) controller is labeled as the PLC. The (f) manipulated variable is labeled as the pressure developed by the fluid flowing through the orifice plate. The (g) measured variable is the flow rate of the liquid.
