5. Apply Stability Criteria, including Routh-Hurwitz, Nyquist, and Bode Plots
The chapter discusses stability in control systems, emphasizing various criteria for evaluating stability including the Routh-Hurwitz Criterion, Nyquist Criterion, and Bode Plot Method. Each criterion provides distinct insights into system behavior, aiding engineers in ensuring the reliability and robustness of control systems. By applying these criteria, one can effectively analyze system stability and optimize control system designs.

What we have learnt
- Stability in control systems is essential for returning to equilibrium after disturbances.
- The Routh-Hurwitz Criterion provides a time-domain method for assessing stability by analyzing poles.
- Nyquist and Bode Plot methods are effective frequency-domain approaches that facilitate stability analysis in feedback systems.
Key Concepts
- -- Stability
- The ability of a system to return to a desired state after being disturbed.
- -- RouthHurwitz Criterion
- A method for determining system stability based on the characteristic equation's coefficients.
- -- Nyquist Criterion
- A frequency-domain method that uses the Nyquist plot to assess the stability of feedback systems.
- -- Bode Plot
- A graphical representation that shows how gain and phase shift vary with frequency, used to evaluate system stability.
