利用模糊理论改善电子调速器控制性能

柴油机电子调速器一般采用PID（比例、积分、微分）算法控制,为了提高系统的调速性能,在系统过渡过程的不同阶段控制器应取不同的增益,即应实时校正PID的参数。在实际系统中,校正的方法可通过分析被控量的测量值,然后查询校正表进行。但要获得一个精细合适的校正表,须通过大量实验,工作量很大,调整也很不方便。本文利用Fuzzy（模糊）理论对电子调速器PID控制的参数进行实时校准,使电子调速器的控制性能得到改善。

Promotion of Performance of Electronic Governor by Use of Fuzzy Theory

Diesel electric governor's control system often adopts PID regulation arithmetic. For improving the system s performance, the controller has to adopt different gain during the different period of system s transition process; the parameters of PID have to be real time modified. In practice, the modification can be done by table look-up after analyzing measured data. It is not ease because a lot of experiment has to be made for gaining an accurate table. The paper makes a research about the real time modification of parameters under the electro-governor (PID) control by use of Fuzzy theory.
