Struct Controller

pub struct Controller<T> { /* private fields */ }

Used for adaptive step size control

Implementations

impl<T: FloatNumber> Controller<T>

pub fn new( alpha: T, beta: T, fac_max: T, fac_min: T, h_max: T, safety_factor: T, posneg: T, ) -> Controller<T>

Creates a controller responsible for adaptive step size control.

Arguments

• alpha - α coefficient of the PI controller
• beta - β coefficient of the PI controller
• fac_max - Maximum factor between two successive steps
• fac_min - Minimum factor between two successive steps
• h_max - Maximum step size
• safety_factor - Safety factor of the PI controller

pub fn accept(&mut self, err: T, h: T, h_new: &mut T) -> bool

Determines if the step must be accepted or rejected and adapts the step size accordingly.

pub fn h_max(&self) -> T

Returns the maximum step size allowed.
