Classical Analysis and Design
Mathematica provides a full suite of tools needed for the classical analysis and design of control systems, leveraging Mathematica's hybrid symbolic-numeric arithmetic capabilities as well as high-quality visualization methods. Built-in frequency response analysis tools include Bode, Nyquist, and Nichols plots, as well as singular-value visualization.
RootLocusPlot plot root locations as a parameter varies
Frequency Responses
BodePlot magnitude and phase plots of the frequency response
NyquistPlot polar plot of the frequency response
NicholsPlot magnitude vs. phase plot of the frequency response
GainPhaseMargins compute gain and phase margins
SingularValuePlot plot singular values of the frequency response
