Consider a 3rd order transfer function (with numerical values) with at least two poles on the imaginary axis and perform the following operations. a) Write the MATLAB code to translate the transfer function and plot the step response? 2 b) Plot the root locus. Based on the root locus plot, what are the dominant poles of the transfer 2 function found in (a))? c) Plot the phase-frequency response from the transfer function in (a) and find the maximum 2 magnitude at the resonant peak? Note: Type the answers in the given space here or upload the scanned copy of your hand-written or typed answer along with typed MATLAB codes in one file). Remember, individual students will have different assumptions of the values, so, avoid copy- paste, otherwise, the answer will receive a zero mark. Make sure describe the detail 1 procedures in your answer as applicable to get partial marks in case if the answer is not completed. Make sure you type/write the answer next to the question number, e.g., Q21(a), Q22(b) and so on.
