So the solution is present above, but I'm having issues understanding the Nyquist Plot. So here's what I know from the magnitude and phase graphs: At \$\omega = 0\$, \$G = |\infty|\$ At \$\omega ...
I am simply using a DAC and trying to generate a DC voltage with it. However, the output is unstable from time to time, with very strange diagram on the scope. The diagram is as below. Could I ask ...
The characteristic equation of a control system is $$s^5+15s^4+85s^3+225s^2+274s+120$$. What are the number of roots of the equation that lie to the left of the line \$s+1\$? My view: I have done ...
