Temperature control system of waste burning within Cement kiln usually uses traditional PID , which often results general effect.When the difference between real temperature and given temperature is large , PD control should be chosen.Other-wise, improved PID control should be chosen.The improved PID controls temperature system of waste burning within Cement kiln by choosing different control schemes, which avoids the defect of traditional PID, and achieves a better control result.%水泥窑垃圾焚烧控制一般采用传统PID控制，其控制效果一般。因此对传统 PID提出改进，当实际温度和设定温度差值较大时采用PD控制，而当温度差值较低时采用增量式 PID控制。改进型PID控制算法，通过对控制方案的选择，对水泥窑垃圾焚烧控制系统进行控制决策和判定，避免了传统PID控制的缺点，达到了提升控制性能的效果。
