 Figure Q2 shows a closed loop feedback model of a physiological

Figure Q2 shows a closed loop feedback model of a physiological system. It consists of one large closed loop and one small closed loop. Demonstrate your understanding of modeling and analysis of the given physiological system by answering the following questions. Figure Q2 (a) Determine the overall transfer function in its simplest form in terms of error , disturbance d and gains A,B and C. (14 marks) (b) Determine the overall transfer function for the TWO (2) extreme cases when disturbance d is very large and very small compared to error and gains A,B and C. For each case, comment on the dependence of the overall transfer function on gain B. ( 6 marks) (c) Determine the overall transfer function in the simplest form in terms of error , disturbance d and gains A,B and C when the feedback is cut at E. (10 marks)
