HW 2

Q5. Consider the Nyquist plot of the frequency response of the open-loop system 10000 G.(s) (s+ 1)(s+10)(s + 50) which is shown in Figure Q5 below. Imaginary Axis 0.5 Real Axis -08 -0.5 -0.5 Figure Q5 2 Tutorial 2: Frequency Response Analysis (a) Write down the expression of the frequency response for this system, clearly showing the overall gain. (b) Is the corresponding closed-loop system with unity feedback gain stable or not? Explain why. (c) Determine the approximate value of the gain margin from Figure Q5. What is the maximum value of an additional gain K for which the closed loop would still be stable? (d) Determine the approximate value of the phase margin from Figure Q5. Assuming that the corresponding point on the plot occurs at 12rad/s, what is the maximum delay which can be added to the system before the closed loop would become unstable?

The Arecibo radio telescope in Puerto Rico is observing the radio spectrum of a distant star. It observes an anomaly at a frequency of 28 MHz. What wavelength of light does this correspond to in base Sl units? *Give answers to at least three significant figures. DO NOT submit answers in scientific notation. Use symbols for units (i.e. m, s, kg, N)* Your Answer: Answer units
