摘要
针对火电厂给水加药过程的复杂性、较大迟延性及难以确切描述的非线性,提出将模糊控制与常规PID控制相结合的新思路,设计了自适应模糊PID控制模型,通过现场实际采集的历史数据,对系统进行仿真分析.结果表明,这种新的控制策略可以很好地处理pH中和过程的非线性和滞后性问题.
According to the complexity,multi-indeterminacy and un-described nonlinear of feedwater automatic adding medicament process in thermal power plant,this paper introduces a new control strategy combining fuzzy control and conventional PID,designed self-adaptive fuzzy PID control model,simulation is studied by collecting the historical data from field engineering.And the simulation results illustrate that the method can settle the delay and nonlinear question of PH neutralizing process effectively.
