Target martensite fraction.

§t_hot: f64

Temperature setpoint for full austenite [K].

§t_cold: f64

Temperature setpoint for full martensite [K].

§kp: f64

Proportional gain for temperature error.

§temperature: f64

Implementations§

Source§

impl SmaController

Source

pub fn new( sma: ShapeMemoryAlloy, t_hot: f64, t_cold: f64, kp: f64, max_power: f64, ) -> Self

Create an SMA controller.

Source

pub fn set_target(&mut self, xi_target: f64)

Set target martensite fraction.

Source

pub fn compute_power(&self) -> f64

Compute heating power to achieve target (bang-bang + proportional).

Source

pub fn step(&mut self, dt: f64, r_thermal: f64, t_ambient: f64)

Step the controller by dt [s] with thermal resistance R_th [K/W]. t_ambient is environment temperature [K].
