Advanced hierarchical multi-objective control for boiler-turbine systems

System Dynamics Overview

The following equations describe the system dynamics that govern the behavior of the boiler-turbine system:

ẋ₁ = -0.0018u₂x₁⁹⁸ + 0.9u₁ − 0.15u₃

ẋ₂ = (0.073u₂ − 0.016)x₁⁹⁸ − 0.1x₂

ẋ₃ = 141u₃ − (1.1u₂ − 0.19)x₁

y₁ = x₁

y₂ = x₂

y₃ = 0.05(0.13073x₃ + 100aₓₛ + qₛ/9 − 67.975)

These equations model the dynamics of steam pressure, electrical power output, and thermal-fluid processes, ensuring optimal control based on real-time system states.
