Bode diagram are the third method (root locus and nyquist Methods are the other two), used to design a stable closed-loop system. Bode diagrams are similar to the nyquist diagrams, in the sense that we plot the phase and magnitude of the open- loop Ta, but this time against the frequency In comparison with the nyquist diagrams, the bode diagrams contain additional information about the system in the frequency data. Knowing the Bode diagram one can construct the corresponding nyquist diagram, but the reverse is not possible Consider the closed-loop system described below 只 G HBode diagram are the third method (root locus and Nyquist Methods are the other two), used to design a stable closed-loop system.
