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?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
