Question

Consider the second-order system Y(s) R(s 2s +1 USE MATLAB ONLY PLEASE Obtain the Unit-Impulse response curves for S-0.1,0.3,0.5, 0.7, 1.0 and 4.0. All graphs should be displayed on single graph property label. Consider the second-order system Y(s) ko Assuming that ωη- 2 and K-2. Obtain the Unit-Impulse response curves for,-0.1, 0.3, 0.5, 0.7, 1.0 and 4.0. All graphs should be displayed on single graph property label. Describe for each system the Transient and steady state response. Remember the Natural and forced response for each case.
