🔋 V–I Envelope Example

🧭 Scenario Overview

A system experiences battery degradation during operation.

The degradation primarily affects voltage (V),
while current capability (I) initially remains available.

This example illustrates how Envelope Control reacts without optimization.

⚡ Initial Condition

Quantity	Status
🔋 Voltage (V)	Within nominal range
⚡ Current (I)	Fully available
🧠 FSM State	🟢 NORMAL

All control modes are permitted.

---

⚠ Voltage Warning Threshold Crossed

As battery degradation progresses:

• 🔋 Voltage drops below the warning threshold
• ⚡ Maximum current remains available

Resulting System Behavior

Aspect	Effect
🧠 FSM State	🟡 WARNING
🦾 Control Authority	Constrained
🚀 Thrust	Limited
🔄 Maneuvers	Aggressive actions prohibited

The system does not attempt to compensate by:

• increasing duty cycles,
• demanding higher currents,
• or relaxing envelope constraints.

---

🚫 Voltage Limit Exceeded

If voltage continues to decline:

• 🔋 Voltage drops below the limit threshold

Resulting System Behavior

Aspect	Effect
🧠 FSM State	🟠 DEGRADED
🎚 Control Mode	Fixed safe mode
🔁 Adaptation	Disabled
🛡 Priority	System survival

Only predefined, certified behaviors are allowed.

🛑 Key Observation

No optimization or recovery attempt is performed
beyond the defined V–I envelope.

The system accepts reduced capability
instead of risking irreversible damage.

💡 Envelope Control does not ask:
“How can we still achieve performance?”

It asks:
“What is the safest action that remains admissible now?”
