Struct VirtualPid 

pub struct VirtualPid { /* private fields */ }

A standalone position-form PID controller, for closed-loop validation and demos (e.g. “do the constants a completed MRFT run just calculated actually control this process well?”). Deliberately not wired into SimulatorDriver/Driver at all: the Driver trait models open-loop tag I/O, and during an actual MRFT relay test the engine itself (bhtune_core::mrft::MrftEngine) drives the MV – nothing needs to close the loop automatically for that. This exists for whatever, later, wants to run this process in automatic mode instead (e.g. simulating a completed tune’s results before trusting them against a real DCS).

Implementations

impl VirtualPid

pub fn new(config: VirtualPidConfig) -> VirtualPid

pub fn step(&mut self, setpoint: f32, pv: f32, dt: f32) -> f32

Computes one control step given setpoint/pv and the elapsed time dt (seconds) since the previous call, returning the clamped controller output.

Derivative acts on pv, not on the error, so a setpoint change alone never spikes the output – mirrors Model/ProcessModelOPC.py’s own D = -Kc*tauD*(pv[i]-pv[i-1])/dt (mathematically equivalent to derivative-on-error only while the setpoint itself is unchanging). The very first call has no previous pv to compare against, so derivative action is skipped for that call only.

Trait Implementations

impl Clone for VirtualPid

fn clone(&self) -> VirtualPid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VirtualPid

impl Debug for VirtualPid

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

Formats the value using the given formatter.

impl PartialEq for VirtualPid

fn eq(&self, other: &VirtualPid) -> 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.
