Root locus and bode plot
WebThe root locus plot does not depend on the sampling period: For strictly proper systems, the root loci go to infinity with straight-line asymptotes: For the strictly proper system, the number of poles is greater than the number of zeros: ... The Bode magnitude plot is the intersection of the surface and the -plane: Web11 Mar 2024 · Here in lies the utility of Bode plots; they depict a range of different frequency responses in two plots. This allows a relatively rapid determination of system robustness. In addition, frequency response and Bode plot analysis can be used to tune PID control systems. Frequency Response
