摘要
针对发电用气体发动机的调速系统,简述原理和系统组成,并提出了一种基于模糊PID算法的控制策略。该系统提出了一种模糊控制改进算法,对电子调速器PID参数按调速系统过渡过程进行在线实时模糊自整定。Matlab仿真结果表明,较常规PID控制系统,该系统具有控制灵活、响应快和适应性强等优点。
Aiming at the speed system of gas engine used in electricity generation, its composition and operation principles are briefly described. A control strategy based on fuzzy PID algorithm is put forward. The system presents an improved algorithm of fuzzy control, the PID parameters of digital governor speed control system, according to the transition process of on-line fuzzy self-tuning. Computer simulation by MATLAB shows that the system has the advantages of reducing steady state error, the control precision is improved and the overshoot is reduced compare with the normal PID control system.
