Struct SogiPll 

pub struct SogiPll { /* private fields */ }

Second-Order Generalized Integrator Phase-Locked Loop (SOGI-PLL).

Implements orthogonal signal generation ($v_\alpha, v_\beta$) from a single-phase input $v(t)$ and tracks fundamental frequency and phase in real-time.

Discretized using trapezoidal (Tustin) integration for zero frequency warping at the center frequency.

Implementations

impl SogiPll

pub fn new( center_freq_hz: f32, sample_rate_hz: f32, k_sogi: f32, kp: f32, ki: f32, ) -> Self

Creates a new SOGI-PLL tuned to center_freq_hz at sample_rate_hz.

• k_sogi: SOGI damping factor (default 1.414).
• kp: Loop filter proportional gain (e.g. 60.0).
• ki: Loop filter integral gain (e.g. 1400.0).

pub fn process(&mut self, input: f32) -> f32

Process a single input sample and return the tracked instantaneous phase $\theta \in [-\pi, \pi]$.

pub fn frequency_hz(&self) -> f32

Returns the estimated fundamental frequency in Hz.

pub fn orthogonal_components(&self) -> (f32, f32)

Returns the filtered orthogonal components (v_alpha, v_beta).

pub fn phase(&self) -> f32

Returns the instantaneous phase $\theta \in [-\pi, \pi]$.

pub fn reset(&mut self)

Reset PLL internal states.
