摘　　要：如今,环境保护日益重要。燃煤电厂的湿式电除尘器可降低烟尘排放,但其烟尘排放过程存在系统时延、干扰等因素往往出现排放超标等问题。本文针对湿式静电除尘器展开闭环控制方法研究,提出一种简单直观的一阶加时延自抗扰控制调参方法,所提出的调参法基于带宽参数化技术,进一步使用缩放技术简化增益整定规则和稳定性分析过程,并且详尽地分析了闭环系统的鲁棒性度量,揭示了相对时延裕度在调参过程中的关键作用。研究结果表明,该方法解决一类一阶加时延的湿式静电除尘器出口烟尘浓度的控制问题,其闭环系统的鲁棒性、控制效果良好。Nowadays,environmental protection is becoming increasingly important.The wet electrostatic precipitator in coal-fired power plants can reduce dust emissions,but dust emission process suffers from system delay and disturbance,leading to emissions exceeding standards.This article proposes a simple and intuitive first-order time-delay active disturbance rejection control tuning method for wet electrostatic precipitators.The proposed tuning method is based on bandwidth parameterization technology,and further simplifies the gain tuning rule and stability analysis process using scaling technology.The robustness indexes of the closed-loop system is analyzed in detail,which reveals the key role of relative delay margin in the gain tuning process.The research results indicate that this method solves control problem of the outlet dust concentration of wet electrostatic precipitator systems,and has good robustness and control performance for the first-order time-delay systems.
