摘　　要：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回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。Considering poor intuition and readability and traceability of existing basic loop controller＇ s performance evaluation method, a multi-index-based comprehensive 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.
