提出了一套新的工具，包括控制器缩放、控制器参数化和实用优化，用于规范控制器的整定。控制器缩放用于对一大类对象的现有控制器进行频率缩放，从而省去了对主要在增益和带宽方面存在差异的对象进行重复的控制器整定过程。控制器参数化使控制器参数成为单个变量（回路增益带宽）的函数，极大地简化了整定过程。实用优化是指在物理约束条件下使带宽最大化，这些物理约束条件决定了性能的限制因素。总体而言，这些新工具使控制器整定朝着科学化的方向发展。
A new set of tools, including controller scaling, controller parameterization and practical optimization, is presented to standardize controller tuning. Controller scaling is used to frequency-scale an existing controller for a large class of plants, eliminating the repetitive controller tuning process for plants that differ mainly in gain and bandwidth. Controller parameterization makes the controller parameters a function of a single variable, the loop-gain bandwidth, and greatly simplifies the tuning process. Practical optimization is defined by maximizing the bandwidth subject to the physical constraints, which determine the limiting factors in performance. Collectively, these new tools move controller tuning in the direction of science.
