Control Theory
The mathematical backbone of autonomous systems. Control theory provides the rigorous framework for ensuring AI systems remain stable, predictable, and safe in real-world deployments.
The Feedback Loop
At the heart of control theory is the closed-loop system: continuously measuring outputs and adjusting inputs to achieve desired behavior.
The Classic Control Equation
PID Controller: Proportional + Integral + Derivative
The Pillars of Control Theory
These fundamental concepts form the foundation for designing systems that behave predictably and safely.
Stability
Ensuring the system returns to equilibrium after disturbances—the foundation of reliable autonomous operation.
Controllability
The ability to drive the system from any state to any other state using available inputs within finite time.
Feedback
Using output measurements to adjust inputs, enabling self-correction and adaptation to changing conditions.
Observability
The capability to infer the complete internal state of a system from its outputs and inputs.
Modern Control Approaches
From classical PID to learning-based methods, control engineers have developed diverse tools for different challenges.
