Abstract

The boiler steam pressure is an important parameter reflecting the state of boiler operation. Considering the disturbance and uncertainty of the fuel-steam pressure system, only using pressure signal, an extended state observer is designed, and sliding mode controller is designed based on disturbance and uncertainty compensation. From Lyapunov stability analysis, it is shown that the closed system stability can be guarantee. Simulation results are presented to validate the good system robustness and good tracking performance of the control system.
