这项工作研究了基于识别的比例、积分和微分 (PID) 控制器整定。开发了一种不使用测试信号的闭环 PID 整定方法。其基本思想是在闭环测试中适当改变PID控制参数以达到持续励磁条件。这样不仅可以在不使用外部激励信号的情况下准确识别闭环系统，而且可以提高测试过程中的控制性能。引入随机模型误差界用于模型验证。应用内模型控制设计方法来整定PID参数。通过模拟说明了所提出方法的有效性。
Identification‐based proportional, integral, and derivative (PID) controller tuning is studied in this work. A method of closed‐loop PID tuning without using test signals is developed. The basic idea is to shift the PID control parameters properly to achieve persistent excitation condition in closed‐loop test. In this way, not only the closed‐loop system can be identified accurately without using external exciting signals but also the control performance can be improved during the test. A stochastic model error bound is introduced for model validation. An internal model control design method is applied to tune the PID parameters. The effectiveness of the proposed approach is illustrated by simulations.
