| 摘 要： | 气化炉是洁净煤发电系统的关键设备,其控制水平直接影响到电站整体的安全和效率。针对ALSTOM能源技术中心发布的气化炉控制基准问题,从控制系统设计的角度出发,对其非线性、耦合性和抗扰性进行了定量分析。结果表明:该系统具有一定的非线性,对控制器的鲁棒设计有较高的要求;系统具有强耦合;通过广义相对扰动增益分析,获得了该气化炉系统的分散和解耦控制结构。上述分析结果对进一步设计和优化控制系统提供了有价值的参考。

| Abstract: | The gasifier is the crucial part of clean coal power plants,so its control directly influences the entire plant safety and efficiency.The nonlinearity,coupling and disturbance rejection characteristics of the ALSTOM gasifier benchmark problem were analyzed to improve the gasifier control system design.The results show that a robust controller design is necessary due to the system nonlinearity and the system has strong coupling.A decentralized,decoupled control structure was developed based on a generalized ... |
