一种新的 PID 控制参数自寻优整定方法——控制品质加权法

提出了一种新的，用于ＰＩＤ控制，以两个控制品质参数（过渡时间Ｔｓ和超调量δ）等权或不等权和最小为整定准则，称为“控制品质加权法”的控制参数自寻优整定方法．多次仿真输出的图形和数据结果充分证明，采用控制品质加权法，比采用ＩＴＡＥ误差准则、ＩＳＥ误差准则和经验乘系数等各种传统方法，都能提供更优的控制参数，从而使系统的控制品质得到明显改善，并能满足对过渡时间Ｔｓ和超调量δ看重程度不同用户的不同要求

A New Method for Self adaptation of the Quality Factors in PID Control

The author advanced a new method,control quality weighting (CQW) method,for the parameters self optimizing adjusting in the PID control system.The key to the new method is that the sum of two control qualities (transient time T s and overshoot δ ) equals to minimum with the same weighting ( T s+ δ) or different weighting (p 1 T s +p 2 δ).A large quantity of data and pictures outputed from multisimulations have shown fully that the controlling qualities get better in the CQW method than in the used methods like ITAE code,ISE code and experiential coefficients etc.Also the new CQW method should be able to satisfy different user's requirements easily,if the users pay more attention to one of the control qualities than to another or they pay regard to both as the same.
