Struct FopdtConfig 

pub struct FopdtConfig {
    pub gain: f32,
    pub time_constant_s: f32,
    pub dead_time_s: f32,
    pub tick_interval_s: f32,
    pub noise_amplitude: f32,
}

Configuration for a FopdtProcess: the classic three parameters process control literature uses to characterize a first-order-plus-dead-time (FOPDT) process, plus the tick cadence and measurement noise needed to turn the continuous model into a discrete one a Driver can serve one sample at a time.

Fields

gain: f32

Process gain (Kp): steady-state change in PV per unit change in MV.

time_constant_s: f32

Time constant (tau), in seconds: how quickly PV approaches its new steady state after an MV change, absent dead time. 0.0 means an instantaneous response (PV reaches its new steady state within a single tick).

dead_time_s: f32

Dead time (theta), in seconds: how long PV takes to begin responding to an MV change at all. Modeled as a whole number of ticks (ceil(dead_time_s / tick_interval_s)), matching Model/ProcessModelOPC.py’s own ndelay calculation. 0.0 disables the delay line entirely.

tick_interval_s: f32

Simulated seconds advanced per FopdtProcess::step call. Deliberately unrelated to real wall-clock time – a caller can call step (via SimulatorDriver::read) as fast as the CPU allows, and the simulated clock still advances at this rate, which is what lets an E2E test run an entire tuning cycle in milliseconds instead of the minutes a real 800ms-tick MRFT test takes.

noise_amplitude: f32

Amplitude of uniform noise (+/- noise_amplitude, in PV engineering units) added to each computed sample, mirroring ProcessModelOPC.py’s noise_amp. 0.0 (the default from FopdtConfig::new) disables noise entirely and skips drawing from the RNG altogether, keeping every sample exactly reproducible run to run.

Implementations

impl FopdtConfig

pub fn new( gain: f32, time_constant_s: f32, dead_time_s: f32, tick_interval_s: f32, ) -> FopdtConfig

A process configuration with no measurement noise. Chain FopdtConfig::with_noise_amplitude to add some, or set the field directly.

pub fn with_noise_amplitude(self, noise_amplitude: f32) -> FopdtConfig

Returns self with noise_amplitude set, for a fluent construction style.

Trait Implementations

impl Clone for FopdtConfig

fn clone(&self) -> FopdtConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for FopdtConfig

impl Debug for FopdtConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FopdtConfig

fn eq(&self, other: &FopdtConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
