A mechanical system has an open-loop transfer function below: GG(ss) = 1 ss2 + 2ss + 20 a) Design a PD compensator to obtain a settling time less than 1s, and overshoot less than 5%. b) Find the closed loop zero and poles of the system for 2 cases; •Without the PD compensator present •With the designed PD compensator in cascade (c) What is the effect of adding the PD controller in terms of the number of zero and poles and their location?

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
