Matlab code to extract damping ratio from the spectrum
PROBLEM 2 Write a Matlab code* (script) or use Excel to determine the damping coefficient of a spring - mass - damper system with a mass of 165 kg and stiffness of 2400 N/m such that its response will die out (decay) after about 1.5 s, given a zero initial position and an initial velocity of 8 mm/s. 1. Display the numerical value of the damping coefficient. 2. Plot the response of the system. *Turn in your Matlab code with...
I only need MATLAB solution with commands
The damping ratio, ^, effects the performance of a system. Using MATLAB, for a single loop second order feedback system, find the step response of the system for values of wn 1 and = 0.1, 0.4, 0.7 , 1.0 and 2.0 E(s) R(s) G(s) Y(s) s(s +2,) Plot all the results in the same figure window and fill in the following table. Rise Time Peak Time % Overshoot Settling Time Steady State Value...
3. For small amount of damping, show that the damping ratio ζ can be approximated from the response curve as 212nωωζω−=. 1ω and 2ω are the frequencies on either side of resonance, where the amplitude is 12 of its maximum value. Explain how you can apply this result to the measurement of damping coefficient.
Please be specific about the root locus and Matlab code.
Problem 2 For the feedback system shown in the diagram below, use the root locus design method to find the value of the gain K that results in dominant closed-loop poles with a damping ratio Ç-0.5- Verify your solution with Matlab, and attach the plotted solution.

An extract from a 'H-1H COSY spectrum is shown below. Use your understanding of NMR to identify which signals are coupled together and suggest which hydrogens of the proposed molecule the signals represent. You have to copy the 'H-'H COSY Extract in your answer booklet and indicate the signals that are coupled together in the copied scheme in the answer booklet.
