Abstract :
This paper focuses on the design of decentralized PID control scheme for the ALSTOM gasifier based on online coal quality analyzing technique. Taking into account characteristics changing with coal quality variations during gasifier operation, corresponding control strategies were added into the decentralized PID control scheme. Simulation results show good control performance for the ALSTOM gasifier benchmark test with fine coal quality signal. The proposed control scheme adopted the traditional PID control algorithm which could be easily implemented. Thus, provides good guidelines for practical control system design for gasifiers that are subject to coal quality variations.
