模糊内模PID控制在湿法脱硫系统中的应用

摘要

For wet flue gas desulfurization control system has nonlinear,time varying,large delay and large inertia and other characteristics.A fuzzy internal model PID wet flue gas desulfurization control system is designed.The simulation results show that this control strategy not only has good dynamic performance and stability performance,but also has stonger model adaptability and anti-interference ability.Its control quality is better than PID control and internal control.%针对石灰石/石膏湿法脱硫系统具有非线性、时变、大迟延、大惯性等特点,设计了模糊内模PID湿法脱硫控制系统.仿真结果表明,该控制策略不仅具有较好的动态性能和稳态性能,而且具有较强的模型适应能力和抗干扰能力,控制品质优于常规PID控制及内模控制.
