已经推导出了单变量前馈/反馈系统的方差分析，该分析能够确定由干扰和控制器所导致的方差贡献。已经开发出一种评估整个控制方案性能的性能指标。可以使用普通闭环数据和最小二乘回归来获得方差分析和性能指标的估计值。这些量可在线或离线用于新控制器的设计，或者作为评估现有前馈/反馈控制方案性能的一种手段。通过模拟数据和工业数据证明了本文结果的实用性。
An analysis of variance for univariate feedforward/feedback systems has been derived which allows the variance contributions due to both disturbances and controllers to be established. A performance index which assesses the performance of the overall control scheme has been developed. Estimates of the analysis of variance and performance index can be obtained using ordinary closed loop data and least squares regression. These quantities can be used on-line or off-line for either the design of new controllers or as a means of assessing the performance of existing feedforward/feedback control schemes. The practicality of the results in the paper are demonstrated using simulated and industrial data.
