    Apply Stability Criteria, Including Routh-Hurwitz, Nyquist, And Bode Plots

    This section discusses stability in control systems and three main criteria for assessing stability: the Routh-Hurwitz criterion, the Nyquist criterion, and the Bode plot method.

  • 5.1

    Introduction To Stability In Control Systems

    Stability in control systems determines a system's ability to return to equilibrium after disturbances and is analyzed using various criteria such as Routh-Hurwitz, Nyquist, and Bode plots.

  • 5.2

    Routh-Hurwitz Criterion

    The Routh-Hurwitz Criterion is a method for assessing system stability based on the poles of its characteristic equation.

  • 5.3

    Nyquist Criterion

    The Nyquist Criterion is a frequency-domain method for evaluating the stability of feedback systems through the Nyquist plot of the system's frequency response.

  • 5.4

    Bode Plot Method

    The Bode Plot Method is a graphical technique for analyzing frequency response in control systems, crucial for assessing stability and performance.

  • 5.5

    Comparing Stability Criteria

    This section discusses three primary stability criteria in control systems: Routh-Hurwitz, Nyquist, and Bode plots, emphasizing their differences and applications.
