3 To control the heading angle of an aircraft the following autopilot loop is to be used. K(s + 1) where a = b = 1 s- + as + b aircraft 1.46 6.56 S a) To draw the root locus plot, use the 4 basic rules from the formula sheet. Determine the open loop poles and zero Rule 1 +/- Real pole at s = Complex poles at s = Real zero at s = Where does a locus exist on the real axis? Rule 2 Rule 3 Asymptotes are at what angle to the positive real axis? +/- deg Asymptotes meet on the real axis at: Rule 4 (16 marks) b) Sketch the root locus plot using the data above. (5 marks) Please attach a photo/scanned copy of your sketch (no sketch = no marks) Given your root locus sketch, which of the following conclusions are true and which are false? c) (0) 1 = true, 2 = false The aircraft in open loop is conditionally stable. The aircraft will be unstable in closed loop irrespective of the value of K The aircraft in closed loop will only be stable whilst the loci are to the right of the vertical axis The aircraft in closed loop is stable assuming Kis positive (ii) (iv) (4 marks)
