⚙️ 2.2 CORE CONTROL LOOP (C++-STYLE)
C++
void loop() {

// 1. Acquire sensor state
State S = readSensors();

// 2. Estimate contamination
float pfas_est = model.predict(
S.turbidity,
S.orp,
S.conductivity,
S.fluorescence
);

// 3. Control law
float reactor_power =
K1 * pfas_est +
K2 * derivative(pfas_est) +
K3 * S.flow_rate;

// 4. Actuation
setPumpPWM(S.flow_target);
setUVIntensity(pfas_est);
setHVReactorVoltage(reactor_power);

// 5. Swarm communication
broadcastNodeState(S, pfas_est);

delay(50); // 20 Hz control loop
}
