Linear Active Disturbance Rejection Control for an ALSTOM Gasifier
Gasifier is a key part of integrated gasification combined cycle power generation technology (IGCC).Its performance directly affects the efficiency of the IGCC.So,it is essential to control the gasifier effectively.Due to its strong non-linearity and large inertia characteristics,ALSTOM gasifier is generally difficult to be controlled with conventional control schemes under all working conditions.Through analyzing its baseline controller,two control schemes are designed to apply the first-order linear active disturbance rejection controller to the system to improve the baseline controller performance.Simulation results show that the proposed control system meets the control requirements,and that it is superior to conventional controller in the real-time decoupling capability and simple structure.
