3. For the position control system shown in Figure 2, find the following: R(s) + K(s+4) S2 + 4s +5 C(s) Figure 2: Block diagram of a position control system (a) Plot the root locus of the system using MATLAB. [5 marks] (b) From the root locus, determine the following: i. The range of K for the system to be stable. ii. The value of K that makes the system marginally stable and the corresponding frequency of oscillation. iii. The range of K for the system to be unstable. [7 marks]
