Design a feedback control system for the plant such that the following three control objectives are all met: objectivel: the steady-state value of the output for input r(t) 1 is at least 0.9; objective2: the output reaches 95% of its final value no later than 0.1s; objective3: the overshot (%mp) is less than 5% r(s) c(s) plant controller 10 h(s) s +10 (a) (25pts) as a first try, consider a simple proportional controller h(s) kp. determine the range of value for kp that meets the three objectives. (b) (25pts) now consider a more complex pl controller hos) kp kl/s. determine a set of kp and kl values that meet the three objectives.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
