Module control 

Control systems: state-space models, transfer functions, stability analysis. Control systems analysis: state-space models, transfer functions, stability analysis, and controller design utilities.

State-Space Models

A linear time-invariant (LTI) system in state-space form: ẋ = Ax + Bu y = Cx + Du

Transfer Functions

G(s) = num(s) / den(s) — a ratio of polynomials in the Laplace variable s.

Structs

StateSpace

A linear time-invariant (LTI) state-space model.

TransferFunction

A transfer function G(s) = num(s) / den(s).

Functions

is_routh_stable

Check Routh-Hurwitz stability: all first-column entries must be positive (or all negative) for stability.

routh_array

Compute the Routh array for stability analysis.
