QUESTION 1 (a) Given a block diagram for space satellite system as shown in Figure Q2(a). To get the desired angle of orientation, a single transfer function of the system Y(s) = (s) is - R(S) obtained. R(s) + H₂(s) H₂(s) G₁(s) S. G₂ (s) H₂ (s) H4(s) G3(s) Hg(s) Figure Q2(a): Space satellite block diagram (1) Construct a signal flow graph for the system in Figure Q2(a). -C(s) C2 [SP1] [4 marks] (ii) Identify the forward path, loop gain, combination of non-touching loop and loop gain that do not touch any respective forward path. C3 [SP2] [6 marks] (iii) By using Mason's rule, find the single transfer function Y(s) for the system if G₁(s) = G₂ (s) = G3 (S) = 2s and H₁ (s) = H₂(s) = H₂(s) = H₂(s) = H₂(s) = C3 [SP1] [6 marks]
