Figure P9.6(a) shows a heat-exchanger process whose purpose is to maintain the temperature of a liquid at a prescribed temperature.
The temperature is measured using a sensor and a transmitter, TT 22, that sends the measurement to a corresponding controller, TC 22, that compares the actual temperature with a desired temperature set point, SP. The controller automatically opens or closes a valve to allow or prevent the flow of steam to change the temperature in the tank. The corresponding block diagram for this system is shown in Figure P9.6(b) (Smith, 2002).
Assume the following transfer functions:
a. Assuming
b. Design a PD controller to obtain the same damping factor as Part a but with a settling time 20% smaller.
c. Verify your results through MATLAB simulation.

Control Systems Engineering
- After some engine model replacement, an aircraft model is experiencing some aggressive nose up phenomenon which may lead to stall. To combat this problem, a new control system has been introduced to the Flight Control Computer, FCC. When activated, the new system measure the aircraft pitch from an Angle of Attack, AOA sensor to analyze either the aircraft is nosing up or down. If the pitch angle is too high, describing that the aircraft might be in a dangerously nose up position, the FCC will gain control of the horizontal stabilizer using a linear motor (FIG 1), thus bringing the nose of the aircraft down into safer pitch angle range (FIG 2). a. What is the input/output of the control system? b. Is this system is a close loop or open loop? c. What is the actuator used in this control system? d.

(More practice from Monday) A 90° elbow in a horizontal pipe is used to direct a flow of oil (SG = 0.87) upward at a rate of 40 kg/s. The cross- sectional diameter of the elbow is a constant 20 cm. The elbow discharges at A into a large holding tank where the level of oil is 1.8 m above A. The 50 cm "weight" of the elbow and the oil in it is 50 kg. Determine (a) the gage pressure at the inlet of the elbow and (b) the anchoring force needed to hold the elbow stationary. Take the momentum-flux correction factor to be 1.03 40 kg/s at both the inlet and the outlet. Activar Windows Ve a Configuración para activar Windows.

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 (1st order) and PFR (dead time) to changes either in inlet temperature, or in the heating/cooling jacket flowrate via Ke-tas 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.
