This could represent the dynamics of an Industrial Remote Inspection System, which is essentially a remote-controlled robot for high radiation fields. Our goal is to design a proper compensator C(s). (a) (7 points) Design a compensator C(s) such that the gain crossover frequency become ωg = 10 rad/sec, and a minimum phase margin of 35 degrees is achieved (Note: tan−1 (10) = 84.3 ◦ , and tan−1 (3.33) = 73.3 ◦ And don’t forget to account for, say, 5◦ additional margin so once you modify your compensator in the next part, you would still meet your minimum phase margin of 35◦ ). (b) (1 point) Find the velocity constant Kv for the compensated system you designed in Part (a). What would be the steady-state tracking error of the closed-loop system ess for a ramp input r(t) = tu(t)? (c) (4 points) Now, modify your compensator in order to further reduce the steadystate ramp tracking error to less than 0.001 while still trying to preserve the same gain crossover frequency and the same phase margin as Part (a). (d) (2 points) How would you propose to modify your compensator in Part (a) if, instead of the 0.001 tracking error requirement in Part (c), your objective was actually to completely eliminate the steady-state error in tracking a ramp input?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
