The exit temperature of the heat exchanger shown below is controlled by adjusting the steam flowrate. Inlet temperature is the only disturbance. The process model is given by: 2.Se TA 0.9e W + 10s +1 -T 5s +1 The valve's dynamics is negligible compared to the process. The following linear relationship holds between the valve output and controller signal that activates the valve: w(t)- w.= 0.40p(1) - P.) where p. = 12mA and w, = 1.71b/sec are the nominal steady states for the valve input and output. The sensor is first order with time constant equal to 4 sec. When its input 7; is a step increase from 120 to 140 F, the sensor output increases from 4 to 20 mA.
