stable system waveform and s-domain plot

Stability of control systems

What is stability of control system ? Stability refers to the ability of a closed-loop system to maintain a state of equilibrium or to return to that state after being subjected to disturbances or changes. A stable control system is one in which the output remains bounded and does not

Routh-Hurwitz Criterion

Routh-Hurwitz Stability Criterion The Routh-Hurwitz Stability Criterion is a mathematical technique employed to ascertain whether a polynomial’s roots lie on the left-hand side of the s-plane. It is a valuable tool as it allows one to assess the stability of a system without finding the roots of the characteristic equation.

Bode plot

What is a bode plot? A Bode plot is a graphical representation of a closed-loop system’s loop-gain LG(s) frequency response. It is a widely used tool in control systems engineering, electronics, and signal processing to analyze and design closed-loop linear time-invariant (LTI) systems. Bode plots provide insights into how a
