Understanding Real-Time Optimal Control

Real-time optimal control involves continuously adjusting the parameters of a system to achieve desired results.
Unlike traditional control methods that rely on fixed rules, real-time optimal control dynamically responds to changes in the environment.
The ability to calculate optimal control strategies as conditions change allows for enhanced performance and adaptability in systems.

Key Concepts

At the heart of real-time optimal control is the optimization problem.
This involves finding the best control action that minimizes or maximizes a specific performance criterion, such as energy consumption or time.
The optimization problem must be solved quickly and efficiently to ensure the system can respond in real time.

To solve the optimization problem, algorithms such as Model Predictive Control (MPC) or Robust Control are frequently employed.
