Project Overview

PHYSIOPT-X is an advanced MATLAB/Simulink-based framework designed for the development of self-verifying, fault-aware, and self-reconfiguring control systems for autonomous cyber-physical systems.

Unlike conventional control projects that focus only on designing a controller and evaluating its performance under nominal operating conditions, PHYSIOPT-X addresses a more challenging problem:

What happens when the system changes, degrades, becomes uncertain, or develops a fault after the controller has already been designed?

PHYSIOPT-X provides an autonomous closed-loop methodology capable of optimizing a controller, monitoring the physical consistency of the system, detecting abnormal behavior, diagnosing possible faults, reconfiguring the control strategy, and mathematically verifying the resulting controller before accepting the recovery.

The framework therefore transforms the traditional control workflow from:

Model → Controller → Simulation → Results

into an intelligent engineering cycle:

The Scientific Problem

Assume we have:

Assume that we have the following mathematical model:

$$ \dot{x} = f(x,u,\theta) $$

where:

• $x$ = system state
• $u$ = control input
• $\theta$ = system parameters

Initially, we have:

$$ \theta = \theta_0 $$

and the controller operates correctly.

However, after some time:

$$ \theta \neq \theta_0 $$

This may occur due to:

• Motor degradation
• Load variation
• Friction
• Sensor bias
• Actuator saturation
• Battery voltage variation
• External disturbances
• Mechanical degradation

As a result, the mathematical model no longer accurately represents the real system:

$$ \text{Model} \neq \text{Reality} $$

This is where the problem begins.

The PHYSIOPT-X Concept

Instead of the system simply stating:

"The controller failed."

It attempts to determine:

Why did the controller fail?

Then:

Can I recover automatically?

Then:

Can I mathematically verify that the recovery is actually better?
