A unique control strategy based on Active Disturbance Rejection Control (ADRC) is introduced to the Shell gasifier control system. Firstly, the gasifier control system structure is illustrated based on the analysis of gasifier process dynamics and its control targets. Then a decentralized ADRC-based gasifier control system is designed and the controller parameter tuning procedure is given. The interaction of control loops, the uncertainties in the plant and the ignored dynamics in modeling process are all regarded as the general disturbance, which can be estimated by Extended State Observer (ESO) and then actively compensated in real time. The performance of the proposed control strategy is tested on a Shell gasifier model by simulation experiments, and the Monte-Carlo method is also adopted to test the robustness of the control system. In comparison with the optimized PI controllers with probabilistic robustness, the simulation results show that the designed control system has advantages of better reference-tracking and disturbance-rejection capability, strong robustness and easy tuning procedure.
