Struct BodeAnalysis 

pub struct BodeAnalysis {
    pub num: Vec<f64>,
    pub den: Vec<f64>,
}

Bode analysis for a transfer function given numerator and denominator polynomials.

Polynomials stored as coefficients in descending order of s: num = [b_n, ..., b_0], den = [a_m, ..., a_0].

Fields

num: Vec<f64>

Numerator polynomial coefficients (descending order of s).

den: Vec<f64>

Denominator polynomial coefficients (descending order of s).

Implementations

impl BodeAnalysis

pub fn new(num: Vec<f64>, den: Vec<f64>) -> Self

Create a Bode analysis object.

pub fn eval_at(&self, omega: f64) -> (f64, f64)

Evaluate transfer function G(jω) at angular frequency ω.

pub fn compute(&self, omegas: &[f64]) -> Vec<BodePoint>

Compute Bode points at the given frequencies.

pub fn compute_log( &self, omega_min: f64, omega_max: f64, n_points: usize, ) -> Vec<BodePoint>

Compute logarithmically-spaced Bode plot from ω_min to ω_max with n_points points.

pub fn margins( &self, omega_min: f64, omega_max: f64, n_points: usize, ) -> (f64, f64)

Find gain margin (dB) and phase margin (degrees).

• Gain margin: gain (dB) at the phase crossover frequency (where phase = -180°).
• Phase margin: phase (deg) + 180° at the gain crossover frequency (where gain = 0 dB).

Returns (gain_margin_db, phase_margin_deg).
