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.

基于在线煤质分析仪的阿尔斯通气化炉分散PID控制
本文主要研究了基于在线煤质分析技术的阿尔斯通气化炉分散PID控制方案的设计。考虑到气化炉运行过程中煤质变化所带来的特性变化,在分散PID控制方案中加入相应的控制策略。仿真结果表明,采用细煤质信号的阿尔斯通气化炉基准试验具有良好的控制性能。该控制方案采用传统的PID控制算法,易于实现。因此,为煤质变化的气化炉的实际控制系统设计提供了良好的指导。
