  • 摘要: 工业控制系统性能评估关系到工业生产安全与企业绩效. 工业过程扰动频繁且存在时变特性,多变量时变扰动系统缺少统一有效的性能评估方法. 本文提出了基于多模型混合时变最小方差(Multi-model mixing time-variant minimum variance, MMTMV)的多变量系统性能评估方法. 首先,根据扰动作用起止时间设定混合权重,基于多模型混合的思想利用混合权重与每一时变扰动特性设计多变量MMTMV控制器. 然后,利用多变量MMTMV控制器得出各被控变量输出方差,将多变量MMTMV控制器下被控变量的平均方差作为性能评估的基准. 最后,本文通过在裂解过程和精馏过程中的控制性能评估应用,验证了多变量MMTMV评估方法的有效性.
