Abstract: A method includes obtaining information identifying (i) uncertainties associated with multiple time-domain parameters of a model and (ii) time-domain performance specifications for a model-based industrial process controller. The model mathematically represents a MIMO industrial process. The method also includes generating multiple tuning parameters for the controller based on the uncertainties and the time-domain performance specifications. The tuning parameters include vectors of tuning parameters associated with the controller, and each vector includes values associated with different outputs of the industrial process. The time-domain parameters could include a process gain, a time constant, and a time delay for each input-output pair of the model. The time-domain performance specifications could include requirements related to worst-case overshoots, settling times, and total variations. The uncertainties could be specified as intervals in which the time-domain parameters lie.
Abstract translation: 一种方法包括获得识别（i）与模型的多个时域参数相关联的不确定性的信息，以及（ii）基于模型的工业过程控制器的时域性能规范。 该模型在数学上表示MIMO工业过程。 该方法还包括基于不确定性和时域性能规范为控制器生成多个调谐参数。 调谐参数包括与控制器相关联的调谐参数的向量，并且每个向量包括与工业过程的不同输出相关联的值。 时域参数可以包括模型的每个输入 - 输出对的过程增益，时间常数和时间延迟。 时域性能规格可能包括与最坏情况超调，建立时间和总体变化有关的要求。 不确定性可以被指定为时域参数所在的时间间隔。
