针对目前基础回路控制器性能评价方法存在直观性差、易读性差和不可溯源的问题,提出一种多指标性能评价方法。采用相对性能指数评价冋路的响应和设定值跟踪情况,采用振荡指数指标评价回路振荡情况,采用有效投用率评价控制器的投用情况。仿真与工业应用结果均证实了所提方法的可行性和有效性。

Abstract:
Considering poor intuition and readability and traceability of existing basic loop controller’s performance evaluation method, a multi-index-prehensive evaluation method was proposed. Having relative performance index adopted to evaluate both loop response and the set point’s tracking ability was implemented, including having oscillatory index employed to evaluate closed loop’s oscillation feature and the effective service index taken to evaluate the controller’s application effect. The simulation and industrial application results verify both feasibility and effectiveness of this method proposed.
