摘要
基于模糊控制技术和汽轮机DEH系统的数学模型,将模糊自整定理论应用于汽轮机DEH系统,设计了一种适用于汽轮机数字电液控制系统的模糊自整定PID控制器。他利用偏差及偏差变化率作为模糊控制器的输入,并制定了模糊规则进行控制,实现PID参数的实时自整定,从而改善汽轮机调节系统的控制特性。仿真结果和分析表明在调节稳定性,超调量和自整定PID参数等方面,模糊自整定PID控制算法均优于传统PID控制算法。
Based on fuzzy control technology and mathematical model of steam turbine DEH system, using fuzzy self - turning theory to steam turbine DEH system, the paper designs a fuzzy self- turning PID controller applied to steam turbine DEH system. Using error and rate of error varying as inputs of the fuzzy self - turning PID controller and making fuzzy rules to control, it can realize the real - time self- turning of PID parameters. The results of simulation and analysis indicate that fuzzy self - turning PID control arithmetic is better than conventional PID control arithmetic in turning stability, overshoot and self - turning PID parameters.
