Abstract:

The control of drum-boiler systems is challenging due to their highly nonlinear dynamics and shrink-and-swell phenomena that complicate level regulation. To this end, a cascade control strategy with feedback action is designed to reduce the effects of contraction and expansion within the boiler, as well as to reduce the effect of disturbances under variable load conditions. The simulation results demonstrate the superiority and reliability of the three-element cascade controller compared to the conventional single-element scheme, achieving faster stability, reducing oscillations, and improving tracking performance. Unlike previous work, this study provides complete mathematical derivations of the fundamental equations and a complete and replicable implementation in MATLAB/Simulink, ensuring both transparency and industrial relevance. The developed simulator provides a robust platform for further research, operator training, and the design of advanced control strategies in thermal power plants.
