摘　　要：针对石灰石石膏湿法烟气脱硫系统中吸收塔浆液PH值变化过程中的高度非线性、滞后性以及各种不确定性,常规PID控制难以达到满意的控制要求,提出一种基于单神经元控制器的控制方案。利用MATLAB仿真工具,编写了单神经元控制算法的S函数程序进行仿真。仿真结果表明:与常规PID控制相比,基于单神经元控制器的吸收塔浆液PH控制系统具有快速响应能力,无超调、无静差并且结构简单易于工程实现。A control scheme based on single neuron controller is put forward by analyzing the PH control system of absorption tower in wet limestone scrubbing,which difficult achieving satisfactory control requirements with the conventional PID control. It was simulated by MATLAB with writing a single neuron control algorithm S-function program. The experiment results show that the control system based on the single neuron control has rapid response ability and is almost with no static error and overshoot. As well as,it makes the adjustment time shorter and easier to implement.
