Write a MATLAB program to obtain the Unit-step and the Ramp response. Create a WORD document and include the MATLAB code and graph of the responses. Consider the tachometer feedback control system shown below. obtain the Unit-step response curves when the tachometer feedback variable K assumes five values: K = 0.1, 0.2, 0.3, 0.4, and 0.5 Create a WORD document and include the MATLAB code and graph of the responses.
