R(s) T D(s) T GZOH(S) G(s) 9.4 (s+4.5) s (s+11.1) H(s) Q1) Consider the system given above with D(s) : answer the following questions. a) Find the open-loop and the closed-loop transfer functions of the system when the sampling switches are closed and the ZOH block does not exist (in other words in the situation of continuous-time control system). Simulate the unit step response of the continuous closed-loop system in MATLAB/Simulink. Provide the screenshot of your block diagram in Simulink. Plot the output signals of the system. ‚G(s) C(s) = 54,H(s) = 1 and S+4 b) Find the bandwidth frequency of the continuous closed-loop system. Determine the sampling period (7) of the digital control system with respect to that frequency, which is appropriate for emulation design with Tustin Transformation. (You can find the bandwidth frequency via using a Matlab command.) c) Obtain the discrete transfer function D(z) of the controller employing Tustin Transformation with the T' you determined in (b) above.
