Struct signalo_filters::filter::observe::AlphaBeta

pub struct AlphaBeta<T> { /* fields omitted */ }

An Alpha-Beta filter.

Methods

impl<T> AlphaBeta<T> where     T: Zero,

pub fn new(alpha: T, beta: T) -> Self

Creates a new AlphaBeta filter with given r, q, a, b, and c coefficients.

Note: Values of alpha and beta typically are adjusted experimentally. In general, larger alpha and beta gains tend to produce faster response for tracking transient changes, while smaller alpha and beta gains reduce the level of noise in the state estimates.

Coefficients:

• alpha: the alpha coefficient
• beta: the beta coefficient
