摘　　要：制浆碱回收白泥煅烧过程具有非线性、大惯性、纯滞后等特点,广义预测控制技术是一种有效的自我调节控制技术。比较传统PID控制方法很难达到理想的效果,提出了一种基于广义预测的自适应PID控制器,通过在MATLAB环境下的计算机仿真,表明该控制器具有响应迅速、鲁棒性好、自适应能力强等优点。Alkali-recovery process in the lime mud rotary kiln system, has large inertia pure retardation and nonlinear characteristics. It＇s hard to get ideal effect with traditional PID, in order to acquire effective auto-adjustment control technique, the paper put forward a generalized predictive PID controller that has the capability of self-studying and self- adapting used in the lime mud rotary kiln system. The computer simulation in MATLAB was found that this controller could obtain faster response, better performance strong self-adaplability,so the practicality and validity of this new controller used in the lime mud rotary kiln control were proved.
