摘　　要：用最小方差准则来评价控制器的性能,仅需过程变量的常规闭环操作数据和过程的时间延迟特性。用最小方差准则对两个精馏塔控制系统的性能进行了分析。分析结果表明,最小方差准则是控制器的性能评价方面一个有效的和可行的基准。It only needs routine closed-loop operating data and knowledge of the process time delay using minimum variance as a benchmark in controller performance assessment.The performance of the two controllers of distillation column is evaluated by minimum variance as a benchmark.The results reveal that minimum variance benchmark acts as an efficient and feasible measurement in controller performance assessment.
