Question

Design and critical discussion

Figure (a) shows a two-tank flow process, Figure (b) is the block diagram of the system by considering inflow qi as input and water height in tank 2 (h2) as output. 

If A1=0.6, A2=1.6, R1=0.7, R2=Ro=1.7,

  • Determine the settling time of this system response to a step input, and fill it in the blank (please keep two digitals after the decimal point).
  • Propose at least two different type of changes you can apply to improve this system behavior so that the settling time can reduce to half of its current value. Please discuss and prove with the necessary calculation.
  • What happens with Maximum overshoot after settling time is improved? Discuss the changing of maximum overshoot for each case.
