Lab 1. Using Simulink, add a pole to the second-order system of Prelab 1a and plot the step responscs of the system when the higher-order pole is nonexistent, at LTI Viewer. Normalize all plots to a steady-state value of unity. Record percent 2. Using Simulink, add azero to the second-order system of Prelab 1a and plot the step -20, -10, -5, and -2. Make your plots on a single graph, using the Smulink 200, 20, 10, and -2. Make your plots on a single graph, using the Simulink overshoot, settling time, peak time, and rise time for each response. responses of the system when the zero is nonexistent, at -200, 50, 111 Viewer Normalize all plots to a steady-state value of unity. Record percent overshoot, settling time, peak time, and rise time for each response. 3. Using Simulink and the transfer function of Prelab 3 with a 3, plot the step responses of the system when the value of b is 3, 3.01, 3.1, 3.3, 3.5, and 4.0. Make your plots on a single graph using the Simulink LTI Viewer. Record percent overshoot, settling time, peak time, and rise time for each responsc. 4. Using Simulink and the transfer function of Prelab 4 with a=30, plot the step responses of the system when the value of b is 30, 30.01, 30.1, 30.5, 31, 35, and 40. Make your plots on a single graph, using the Simulink LTI Viewer. Record percent overshoot, settling time, peak time, and rise time for each response
