1.2 A positional control system is shown in the following figure: G(G) Ms) Servo Motor Amplifier The transfer functions which define this system are: G(s)= XXXXXXXXXXs) s+7 M(s)= 's XXXXXXXXXXs)...

1.2 A positional control system is shown in the following figure: G(G) Ms) Servo Motor Amplifier The transfer functions which define this system are: G(s)= 12(1+0.03 s) s+7 M(s)= 's(1+0.03 s) signal-flow graph a) [8 marks] Represent this block diagram b) [7 marks] Derive the transfer function of the system using c) [10 marks] Write and run MATLAB or Octave code to confirm your answer. Submit the code. You may make use of the following functions: - tf -series feedback -minreal d) [2 marks] What is the order of the system e) [10 marks] How would you modify the block diagram if you want to find the speed of the shaft? (Hint: Consider the relationship of the current output, displacement, with the desired output, velocity) as a masons rule
